"There are only so many ways I can dress up that we don't have the players here."

Brendan Rodgers is doing well to hide his frustration, but that quote hits hard.

More from Celtic boss Brendan Rodgers on next week's second leg: "The beauty is, it's a one-off game now. We weren't quick enough, but we know we can win there. We can't wait on the game.

"As I said to the players at half-time, 'if you're going to miss the bus, make sure you run - don't be walking'. Whatever happens, we have to give everything and make sure we're running.

"If it doesn't happen, then we've given everything. But we waited 45 minutes tonight, which surprised me."

On Adam Idah, who was hooked at half-time: "There's no rocket science in it. It's all hard work and preparation and all that leads to confidence. You normally succeed then as a player. It didn't quite go for him first half.

"I wanted a bit more activity in and around the box. Adam is a good, honest boy. He's not started how he'd like, and in games like this here I can't afford to wait."

And on a lack of summer transfer business: "I accept the responsibility as the manager of the club. I can't tell you anything that I'd like to. There are only so many ways I can dress up that we don't have the players here. The privilege is mine to be here.

"It was pretty clear. You don't need to look into the future too far. You know these games are tough and you want to have players in as quick as you can to tackle these situations. It is what it is. I have to accept where it's at. We'll get ready for Saturday and the long haul Sunday."

Celtic host Livingston in the league on Saturday (15:00 BST) before embarking on the long, long, long journey to Almaty for the return leg on Tuesday.

The city sits fewer than 400 miles from the border with China, so Celtic will be in the air for at least 10 hours and will cross multiple timezones before arriving at their destination.

Celtic manager Brendan Rodgers: "We need to improve the squad. There's been clarity around that for a long time. Supporters see that. We do in football. We need to improve.

"This is a performance club. That starts on the field. You do that by getting the very best players you possibly can to allow you to perform. To play a style that excites supporters.

"Hopefully between now and the end of the season, the club will get that and that will support us.

"It's not my decision in the end. I can prepare the team, the staff, and the players that are here who have been fantastic in pre-season. We are all clear on where we need to improve, and for whatever reason we haven't been able to do that.

"We're in this position, we have to accept that and not dwell on it, and try and come through it."

More from Celtic boss Brendan Rodgers on the 'sack the board' chants.

"What I do know is, over many years, 'sack the board' usually means 'sack the manager'. It's normally the manager that goes when that starts to be sung," he says.

"I can only really look at the players we have here, and the performance. We've known for a long time what we've needed as a squad, so I don't want to go into that.

"At the end of the game, we have to shuffle things about to try and make it work. But the players' endeavour in the second half was really good. But at this level, it's more than that.

"Hopefully we can show that. The boys are a great bunch of lads, really honest. They've started the season well, defensively been strong, but tonight offensively we couldn't show those moments of quality to break through."

Celtic manager Brendan Rodgers: "We're disappointed with the result and first-half performance. We didn't start with the intent and mentality we wanted to. We were quite passive.

"We weren't moving as a team as we would like. The second half was better, we started well but couldn't find the breakthrough in the final third of the pitch.

"Of course, you want to take the advantage. I've been here before, having drawn 0-0 in a qualification game - against Rosenborg, a very good team. We went there to qualify and we did, played very well and won.

"There's no doubt we can go there and win. Of course, you want to take an advantage with you, it's still very much in the balance."

It'll be interesting to hear the views from the Celtic manager after that.

He'll no doubt be asked about the transfer situation again and how it potentially impacted tonight.

We're expecting reaction from him soon.

Celtic captain Callum McGregor tells TNT Sports: "First half we were too slow and too passive.

"Second half we started well, on the front foot the whole half. We've still got another game, it's 0-0, we never lost. We have to go there next week and win.

"The connections weren't quite there to get us through the middle. It's on us to go there and qualify now.

"We know how much everyone wants it. It's our job to work [through the anxiety in the stadium] and keep playing."

Kheredine Idessane
BBC Scotland at Celtic Park

Celtic will need to be a whole lot better in Almaty next week if they're to make it through to the Champions League.

In truth, the Parkhead side offered little to worry a well-organised Kairat side who showed just why they were able to get the better of three other sides on their qualifying journey thus far.

Will the Scottish champions become their fourth victims?

Almaty had the better of the chances, with the sole exception of the huge opportunity spurned by Daizen Maeda.

It was an effort that summed up Celtic's night - lacking in conviction, lacking in intensity, lacking in quality.

It will take a big performance next week to get through, and the home fans booed on the full-time whistle. Then came the 'sack the board' chants for good measure.

At this stage, are Celtic losing their gamble not to strengthen more before the Champions League play-off?

Celtic didn't create enough clear-cut chances for me to say they should have won the game, despite having more possession. Kairat defended so well, too.

Rodgers has clearly said this group, playing these two games, are good enough.

They will have another competitive game in their legs [at the weekend] so maybe they will be fitter.

They can take confidence from some of their away games last season - not against Dortmund - and maybe Rodgers needs to be a bit more pragmatic for it.

Feels weird to see Celtic produce such a low expected goals tally.

Especially against this standard of opponent.

So Celtic will have to win next week after making a 3,500-mile trip to Almaty.

Still doable, of course, but it's become a tougher assignment after this result.

Kairat hadn't won an away Champions League qualifier before tonight.

They still haven't, but this is an excellent result for the champions of Kazakhstan.

Boos follow the full-time whistle at Celtic Park.

A pretty poor first-leg display from Brendan Rodgers' men, it must be said.

One minute to go.

Oh wow, Kairat winger Gromyko tries one from range but drills a shot just wide.
