Aberdeen manager Stephen Glass is in confident mood ahead of a huge match for his side.

"I think you can sense it, you can see it as you're driving in, the amount of people in the building already. We feel like we're for the challenge.

"You've got to just focus on the job in hand. There's a game we need to win. Whether you're play for a tenner, or millions, we want to win."

Glass also confirms a couple of signings are "imminent" but won't comment on rumours that forward Marley Watkins is in Aberdeen and on the verge of re-joining the club.

It's that man Hyunseok Hong again as the LASK midfielder goes on a mazy run and breaks through a challenge into the box.

The man from South Korea gets into the box and tries to finish, but goalkeeper Zander Clark makes a big early save.

A big night for the big man who has had a recall to the Scotland squad.

Slight warning early on for St Johnstone as midfielder Hyunseok Hong tries to hook an effort towards goal, but it falls a yard wide of goal.

The away side have started well.

LASK have been forced into a late change, with striker Alexander Schmidt picking up a knock in the warm-up and being replaced with Keito Nakamura.

Qarabag rested a host of players for their domestic 3-0 win over Sebail at the weekend and go with 10 of the 11 who beat Aberdeen 1-0 last Thursday.

There's no Patrick Andrade, so Ismayil Ibrahimli starts in midfield instead after appearing as a substitute in the first match.

St Johnstone boss Callum Davidson tells BBC Scotland: "Liam Gordon had an unusual injury. We were hoping it would clear, but it hasn't in time.

"The line-up's defensive and attacking when it needs to be. We can't win the tie in the first 20 minutes, but we can lose it.

"We need to play the game - not the occasion. We are relaxed about the game, hopefully the players are too."

Celtic's six wins in a row have coincided with the arrival of former England goalkeeper Joe Hart.

He will be hoping for a fifth clean sheet in Netherlands against AZ.

Celtic manager Ange Postecoglou tells BBC Sportsound: "We have put ourselves in a good position but know it's a tough contest here.

"Our form is good and the key thing will be what we do when we have the ball. If we can be really positive and take the game to AZ, we're always a threat going forward.

"If we just try to stop them for 90 minutes, we're asking for trouble.

"The players are gaining more and more confidence and the goals have been spread around several players, which will be important tonight."

Aberdeen manager Stephen Glass makes just one change as his club seek group-stage football for the first time in 14 years.

Right-back Jack MacKenzie is fit after missing Sunday's draw at Tynecastle, replacing injured forward Connor McLennan as Jonny Hayes is pushed further forward.

After four wins in a row, Aberdeen have gone three games without a win.

But all those came away from Pittodrie, where they have won all three - including two in Conference League qualifying.

Qarabag arrive having beaten Sebail 3-0 on Saturday in their second game in the Premyer Liqa and are now unbeaten in seven games this season, including three away from home.

Aberdeen: Lewis, MacKenzie, Gallagher, McCrorie, Ramsay, Brown, Ferguson, Jenks, Ojo, Hayes, Ramirez.

Substitutes: Woods, Ritchie, McGinn, Emmanuel-Thomas, Gurr, McGeouch, Gurr, Campbell, Ngwenya, Hancock.

Qarabag: Magomedaliyev, Bayramov, Medvedev, Medina, Huseynov, Ibrahimli, Garayev, Kady, Zoubir, Romero, Sheydaev.

Substitutes: Balayev, Arazli, Almeida, Mustafazade, Zamora, Ozobic, Gurbanli, Vesovic.

Despite all the euphoria about how well St Johnstone are doing, it should be noted that Callum Davidson's side have yet to win a game within 90 minutes this season.

Their only win in seven came on penalties away to Arbroath in the Scottish League Cup.

Saints have lost two out of their three games at McDiarmid Park - against Galatasaray in Europa League qualifying then to Dundee United in the Premiership on Sunday after a draw with Motherwell.

LASK, who were held to a draw at home by Hartberg in the Austrian Bundesliga on Saturday, are unbeaten in three away games this season domestically and in Europe.

Early concerns about three opening games without a win under new manage Ange Postecoglou have been replaced with the joy of six for Celtic.

Six wins in a row and they travel to Netherlands on the back of a 6-0 thrashing of St Mirren in the Scottish Premiership on Saturday.

AZ were without a domestic game over the weekend after their 2-0 defeat at Celtic Park and play their first competitive home game of the season after friendly wins over OFI Crete, Real Sociedad and Torino.

The final kick-off of the evening is a landmark game for Aberdeen. It is their 150th European tie and without a doubt it is their most important in many years

It is 14 years since the Dons last played in the group stages of a European competition and Qarabag stand between them and the sizeable cash windfall progress in the Europa Conference League would unlock.

It sounds straightforward, but it is far from that against the wily side from Azerbaijan who have shown year upon year that they know their way around the continental stage.

That said, Aberdeen have plenty of reason to believe they can overturn the 1-0 first-leg deficit with home advantage and the backing of a noisy home support even if the bruising schedule of recent weeks has taken its toll on the injury-hit Dons squad.
