Now Leighton Clarkson is on to replace Adil Aouchiche.

He also makes an immediate impact, setting up Jesper Karlsson on the right who sends a stinging drive at goal but Timothy Fayulu is able to palm away.

Gabri Martinez threatens to race clear for 10-man Braga after a poor Max Aarons pass.

But the Rangers full-back recovers, with the help of Connor Barron.

Jack Milne joins Graeme Shinnie in the book for a nasty looking challenge on Gustavo Sangare.

Just seen the replay and thankfully, not as bad as it first looked.

I don't know how much contact is there but one thing is for sure - the intent is there from Zalazar. And I can't believe he's done that and put his team in that position.

A moment of sheer stupidity.

Madness from Rodrigo Zalazar but his red card has given Rangers a wonderful opportunity to go on and win this.

What he was thinking is unclear but Rangers won't care.

Rangers had looked re-energised in this second half before that with James Tavernier's opener giving them a massive lift.

A Europa League lifeline now looks odds on.

A moment of madness from Rodrigo Zalazar. You're never getting away with that, not with VAR about.

The Braga man motions a headbutt towards Nico Raskin without really doing a headbutt, but it's still a red card.

The VAR instruct the referee to go to the monitor and after a few replays he dishes out the red.

Aaaand Graeme Shinnie is booked for his very first challenge.

Talk about making an impact.

Big chance for Kevin Nisbet. Aberdeen square the ball to their striker on the six yard box but he gets his angles wrong and cuts it high and wide.

Triple change immediately after. Graeme Shinnie, Marko Lazetic and Stuart Armstrong are on.

Kevin Nisbet, Topi Keskinen, and Dante Polvara are hooked.

I think Rangers have had opportunities to punish Braga from set-pieces.

Danilo curls a cross to the back post and Youssef Chermiti is there.

Not sure whether he's shooting or passing but the ball goes across goal and is cleared before Djeidi Gassama forces Lukas Hornicek into a save.

And almost a second for Noah! Matheus Aias curls one from the edge of the box but Dimitar Mitov is behind it.

From leading two minutes ago, Aberdeen are on the ropes.

A dangerous ball across the face of goal isn't met by Youssef Chermiti, who is under pressure from his marker, and Danilo boots a Braga defender instead of the ball on the follow-up.

Braga are dominating the ball early in this half, but there's a lack of intensity in the opening minutes of this second period.

Early card for Noah defender Nathanael Saintini in the second half.

Alen Grgic was also replaced at half-time with Matheus Aias.

Away we go again.

They're surviving many thanks to Jack Butland, Rangers.

But if they start dropping deep, if they try to defend the 1-0, I think they're in trouble. I don't think this defence is good enough to withstand Braga coming at them in waves.

I think they have to be brave, within reason - not recklessly go after a second goal. If they sit back, they're going to invite trouble and eventually Butland won't be able to bail them out.

Aberdeen haven't really been tested that much. Noah haven't put them under any intense pressure.

They're dominating the ball, although not many chances being made.

A deserved lead at half-time, I think.

Celtic interim boss Martin O'Neill: "We played really well. There was a period in the game where we were totally dominant, controlling the ball and exuding a lot of confidence, which was lovely to see.

"Obviously going a goal behind, we could have crumbled. We showed character and resilience and then when we got the equaliser, the confidence flooded into the side.

"I said to the players before the game 'you will get a chance to play tonight'. We took that chance.

"I'm obviously thrilled for the team, there's a bit of selfishness attached to it all too. To win away from home is terrific.

"Judging from last season, the format, you are looking for 10 or 11 points to qualify. It won't be easy, but Celtic have two home games and the confidence is in the side now.

"I told my two brothers who came to the game to start my chant, so they must have done so. Might as well enjoy it while it lasts. In the dressing room, the lads are full of it.

"It's hard to say what I thought [when I took charge]. My two daughters were all in on going for it, but my wife said I would probably mess it up. I haven't messed it up so far. It's been great. The results are what you live by and they've been terrific.

"[The new manager] has got some players who are big winners, which is great. I'm sure he will lean on some of those lads and then it's about improving some of the other players.

"The restoration of confidence is big and it's keeping it going after that.

"Winning away from home is terrific - it's not easy away from home in Europe. It gives them belief that they can come and compete."

Celtic did the business earlier in Rotterdam and we've heard from Martin O'Neill.

Here's what he had to say...
