"We played on the outside of their shape really well first half and we got the all important goal.
"We wanted to try and continue this run and we've not got a really exciting tie to come."
"They thought they had one foot in the next round, I felt that last week. I thought there was an overconfidence, we spoke about that."
On match-winner Joe Wright: "He was in such a poor place place on Sunday, he felt like he let everyone down. But in football there's always another game.
"He's the guy who made the difference tonight."

Image source, SNSKilmarnock’s grit in defence has shone once again.
As soon as McInnes’ men took the lead in the Arctic Circle, there was a noticeable lowering of their defensive line as 11 bodies quickly dropped behind the ball for Tromso’s next attack.
Club captain Kyle Vassell and young, surprise starter Bobby Wales both fluffed chances up the other end in the second half, but it never seemed to unsettle Killie.
Every player held their shape well and rarely allowed Tromso a clear sight at goal, while also effectively slowing down play in the latter stages of the tie.
The late introduction of Rory McKenzie was also inspired, as a late last-ditch challenge from the midfielder thwarted a promising Tromso attack.
The Ayrshire side are now within touching distance of the league stage. And it’s down to their battling attitude and tactical nous when out of possession.

After his early red card during Sunday's home defeat to St Johnstone, the 29-year-old popped up with the decisive goal to send Killie into the Conference League play-off.
Wright was also superb throughout in defence, never putting a foot wrong until his late, enforced substitution.
Tromso: Haugaard, Barry, Skjaervik, Guddal, Cornic, Hjerto Dahl, Jenssen, Antonsen, Paintsil, Nordas, Romsaas.
Substitutes: Thomas, Jenseen, Winther, Erlien, Johnsgard, Larsen, Norheim, Nilsen, Psyche.
Kilmarnock: McCrorie, Wright, Mayo, Findlay, Bainbridge, Armstrong, Donnelly, Lyons, Kennedy, Vassell, Wales.
Substitutes: O'Hara, Deas, McKenzie, Watson, Mackay-Steven, Murray, Cameron, Anderson, E. Brown, Polworth.

Around 300 Kilmarnock fans have travelled to Tromso for Killie's Conference League crunch tie, and so far they're enjoying the Norwegian hospitality.
The flags are up while they take over some local bars and they're in good spirits and in good voice.
Killie's opponents have quite a claim to fame, as the world's northernmost top-flight football club, with the city of Tromso inside the Arctic Circle.
Kilmarnock are hoping to get the better of them tonight on their own patch, as they look to keep their European adventure going.
Image source, SNSIt's been a far from convincing start to the season for Derek McInnes' Kilmarnock, who have lost three and drawn two of their five competitive outings.
Still, could the allure of European competition proper inspire Killie to a first win this term and kickstart their campaign?
Bobby Wales' late goal earned them a 2-2 draw in the first leg of the Conference League qualifier against Tromso last week, and they travel to Norway knowing a win would set up a play-off against either FC Copenhagen or Banik Ostrava.
"It shouldn't be beyond Kilmarnock to, at their best, get through this tie tonight," The Times' Michael Grant told the BBC's Scottish Football Podcast.
"But how many times have we been through this with all the Scottish teams and we think that they're in the mix?
"They nearly lost the home leg, it was a kind of saving job right at the end.
"I do worry for Kilmarnock this season, that's five games in still to get a win. It doesn't seem to have ignited for Derek yet and it'll be a real blow for them if they go out of this round, not just financially of course."

Image source, SNSKyle Vassell is relishing the "cup final atmosphere" he expects to experience when Kilmarnock face Tromso for a place in the Europa Conference League play-offs.
The tie is evenly poised after Bobby Wales' added-time equaliser gave Killie a fighting chance in Norway following a 2-2 draw at Rugby Park.
Tromso recovered from Vassell's early opener to take command of the tie but Wales' leveller means Derek McInnes' men - who lost their Europa League qualifier against Cercle Bruges - travel to Romssa Arena with hope of extending their stay in Europe.
"Now this is potentially the last game - we've had our chance in the Europa League that we let slip - it makes it even more important," said Vassell.
"We must not get caught up in it, it's still a game of football, but we need to go out there knowing essentially it could be a cup final atmosphere and we need to match it.
"Everyone's different. I like to probably taper it down and play the game, stay calm and cool, but some boys will need to get fired up and play with a bit of an edge.
"So it's about trying to speak to the right people in the right way and get them in the right headspace."
Some uncharacteristic defensive lapses let Killie down last week after Vassell's opener, but the striker thinks his side showed enough in Ayrshire to feel confident they can hurt Tromso.
"I thought it was going to be a good night for us, just because of the team I'm in and how good we are defensively," he added.
"You know we had such a good record last season and you wouldn't expect us to concede two goals at home, but at the same time, it showed us we can definitely do some damage.
"And we're full of confidence off the back of that result even though it was a draw. They have some good players in defence, but I fancy my chances."
Vassell admitted Tromso having a rest at weekend while Killie lost against St Johnstone is "beneficial, but it is what it is" and the forward is focusing only about glory, not fatigue.
"That's all I've been thinking about, it's all I've been thinking about," he said.
"I'm going to do my best tonight and make sure I can get the team as ready as possible because it's a massive opportunity for us."
Derek McInnes wants his Kilmarnock side to thrive on the pressure of having to beat Tromso in Norway on Thursday night to extend their Conference League campaign into the play-off round.

Kilmarnock manager Derek McInnes has been speaking to the media before Thursday's Conference League third qualifying round second leg against Tromso in Norway.
Here are the key points from the press conference:
The game is "in the balance", with Kilmarnock still very much in the tie after a 2-2 draw in the first leg. McInnes says that while some may think Tromso are "huge favourites" he does not see it that way.
He was annoyed at the manner in which Kilmarnock conceded goals in the first leg and says they "skewed the result" but he thinks his team were the better side.
Feels there is more to come from Kilmarnock and he wants them to play with a cutting edge while being more organised and concentrated.
McInnes adds: "I don't want us to wait a few weeks before we go and show our best and look back at what might have been."
McInnes says Tromso play with energy and build up their play. Their strength is playing well as a team, not standout individuals.
Corrie Nbada has travelled, but McInnes is hoping not to use the defender. Marley Watkins, Liam Donnelly and Gary Mackay-Steven all travelled and are in squad. But Kyle Maggenis has not travelled.

Tromso co-head coach Gard Holme is confident his side's "better pitch" will help give them the edge against Kilmarnock.
The sides are locked at 2-2 for Thursday night's Conference League qualifier return leg in Norway after Bobby Wales netted a last-gasp equaliser last week at Rugby Park.
Like Kilmarnock, Tromso play on an artificial surface.
"It's going to be a physical struggle, there will a be a lot of duels and we want to control the game a little bit more with the ball than we did in the away game," Holme said.
"It's a bigger pitch, a better pitch, so I think that will be a key point. And then, of course, to have long attacks and try to push them a little bit more backwards than we did.
"I think it will be quite tight and tough and it can go both ways of course, but we are confident.
"The feeling in the club is it's a good opportunity for us. We haven't been in European competition for 10 years and nobody is putting us under pressure. So that's a very good position to be in, we’re in an attacking mind."

Around 300 Kilmarnock fans are expected at the Romssa Arena for Thursday's second leg
The Romssa Arena should be almost full tomorrow night for Kilmarnock's Conference League qualifying mission.
Around 5,300 home tickets have been sold while 300 Kilmarnock fans are expected in the away end.
When the Rugby Park faithful arrive in Tromso they’ll find a picturesque, but busy place. Plenty of bars and restaurants to keep them satisfied.
The weather is being kind too, 23 degrees and sunny, which I’m told is highly unusual for Tromso. It’s due to rain on Thursday, so they’ll feel right at home.

There is a train of thought that teams like Killie, St Mirren or Motherwell simply don't have the depth of squad to perform in Europe and maintain league form.
Killie are certainly doing their bit to prove the point as we look like a shadow of the team who finished an impressive fourth last term.
It's far too early to be hitting the panic button, but the manager's recent comment about the budget being spent is a concern.
The desire to keep most of last season's squad is admirable but even the most successful teams freshen their squad every summer.
We look like a team who need to beef up the squad with some new faces, if that means selling Danny Armstrong, then so be it.
Rumours are abound that Danny could be away once we are out of Europe, and that would bring in some welcome funds and free up another wage.
It's another busy week with a tough trip to the frozen Arctic circle, followed by a cup trip to the even colder Fir Park.
Two wins would put the fans in a better frame of mind and have us dreaming once again of a successful season.

Killie fans, we asked for your views after Sunday's defeat to St Johnstone.
Here's what some of you had to say:
Sean: Kilmarnock currently look like a shadow of themselves. Losing goals which could have easily been prevented and lacking killer instinct up front. It is frustrating, but I believe it can be sorted. The players need to start believing in themselves again.
Adam: We need to learn how to hold onto the ball and control games especially at home. Too many players in the penalty box causes mistakes, no out ball. We are far too defensive, no playmaker in midfield and long balls don’t work, and sorry Kyle Vassell isn’t good.
Mark: We badly need to both stick with a settled team and positions, too much tinkering going on again. Plus a right-back and creative midfielder additions needed.
Scott: Five games down, the same style of play in each one, no wins, almost out of Europe, bottom of the league, an away game to Tromso and a league cup tie away to Motherwell awaits - I've got the fear and it's month one of a new season.
Amy: That was a performance from a team, rightly, with one eye on Europe. Not helped by a stupid red card but we have plenty of time to make amends in the league. If we win 0-1 in Tromso on Thursday none of us will remember this game when we're in Copenhagen for the play off. No panic yet - far from it. In Derek McInnes we trust.
Stephen: A performance reminiscent of the relegation season of 2020-21. It's not a blip either. That's one win in our last 10 competitive games. McInnes loves to shoehorn as many centre-halves as possible into the team, but no full-backs. And the difference in movement from our front two compared to Saints' was embarrassing. Hoofball is getting us nowhere.
Jim: For goodness sake leave out the European games as it is getting us nowhere. We have no consistency in team selection. Europe means nothing. The league is our bread and butter. Who really cares if we get thumped in Europe. Play fringe players in Europe not the league.

Image source, SNSKilmarnock manager Derek McInnes told BBC Scotland: "We've not had too many bad days at the office in the last wee while. We're not used to losing here and certainly not in that manner.
"We didn't deal with the front two and we were unnecessarily anxious. I can talk all day long about schedules and the rest of it, but there's still an emphasis to do the job right and we gave ourselves a real uphill task.
"Joe got sent off - an experienced defender making poor decisions - and he's beside himself and apologetic and he feels as if he's done us in. It was so much more difficult.
"It was St Johnstone's day today. We lick our wounds, we have to move on from this quickly. I believe we'll pick up on league form as we go through the season. There's still a trust in what we're doing.
"We're certainly going to have to defend better than what we have done. The Celtic game was different, they're a totally different animal. Today we played a part in losing all three goals and that's something we'll have to get better at.
"The biggest drain in our confidence is losing cheap goals, and that's not something you've been able to aim at us. The reason we're playing in Europe is because we've defended a lot stronger than that, more robustly. We need to get back to being that.
"I was really pleased with the second-half. We showed good energy, fitness and togetherness. We tried to get that goal and in the main we were good. It's hard to find too many positives."
An Adama Sidibeh double helped St Johnstone coast past 10-man Kilmarnock at Rugby Park to pick up their first win of the new Premiership season.
Sidibeh's strikes sandwiched Joe Wright's red card, as the defender was sent off after two yellows in the opening 16 minutes.
It got worse for Kilmarnock in the second-half when they were denied a penalty before conceding one two minutes later, with Benjamin Kimpioka converting.
What did you make of that, Kilmarnock fans? What's happened to your once sturdy defence?
How big an impact is Europe having?
Andrew Petrie
BBC Sport Scotland
Derek McInnes' side only conceded 44 goals last season, with only the Old Firm and Hearts letting in fewer. They've coughed up seven after two games this term.
That does not include the soft goals given away in Europe either. Club Bruges and Tromso both benefitted from gift-wrapped presents from the Kilmarnock defence.
So, what's happened? Joe Wright, Stuart Findlay, Lewis Mayo and Robbie Deas all impressed last season, to the point that McInnes found it hard to drop any of his centre-backs.
His recruitment this summer has backed that up. He's re-signed solid left-back Corrie Ndaba, who is not yet fit, and Sunderland loanee Oliver Bainbridge - another left-back.
The rest of the defence he seemed happy with. Now, the Killie boss might be looking at the transfer market in the final few weeks for some defensive reinforcements.
