Another five minutes added...

The visitors are down to nine men for the briefest time and now Antoine Griezmann is back on, floating a free-kick into the Celtic box. The hosts knock it away but they can't get hold of the ball to get forward.

Antoine Griezmann is being ordered off the pitch by the ref after taking a bang on the head. He doesn't want to go but Felix Zwayer is holding his ground as he is crowded by Atletico players.

Greg Taylor joins in a Celtic attack and cuts the ball back for James Forrest to have a go, but the shot is always rising on its way over.

It's all there for Celtic. They should now get more space in midfield.

I think I'd still take 2-2.

It's massive. This could be a huge turning point.

Celtic need to make this advantage count. They should get more time and space, but if any team can hit them on the break, it's Atletico.

Huge opportunity for Celtic.

The atmosphere in this place has just been cranked up.

Stick or twist?

Rodrigo De Paul was just about to be subbed off and now he's trudging down the tunnel without a replacement.

Booked in the first half for asking the ref to book an opponent, he's now late in a sliding challenge with Paulo Bernardo.

Stefan Savic adds to the caution count for some moaning at the referee.

Greg Taylor is having to drop back and make it a back-five.

Celtic have been giving the ball away too cheaply and too quickly. I'm not sure if it's because players are in new positions and it's limiting their options.

Kyogo looks utterly shattered as he makes way for James Forrest.

Angel Correa is making his way forward again before Liam Scales makes a great sliding intervention near his own goal.

Angel Correa drills one on target and Joe Hart needs to look lively to save with his feet.

Daizen Maeda is the outlet for Celtic again but he gives the ball away by slamming it straight into the nearest defender.

Celtic have done an awful lot of chasing in this second half.

Can they get up the pitch and make a chance?

Alvaro Morata is withdrawn and on comes Argentine forward Angel Correa.

Morata moved on to nine goals for the season with that expert headed finish.

We all know Kyogo doesn't need to be too involved in a game to make an impact.

The Celtic striker has been pretty quiet since his goal, managing just 18 touches so far.

Joe Hart is on 30. Nathaniel Phillips is already on 14.

That's 25 minutes gone in this second half and Celtic are yet to have a shot.

Are they running out of steam after that whirlwind first 45 minutes?

The tireless running of Daizen Maeda forces Jan Oblak to concede a throw-in with a careless clearance.

The Celtic winger must be a nightmare to play against.

We haven't seen Celtic play this three at the back system. It'll be interesting to see how they use the ball as they match Atletico's line-up.

Suddenly, Matt O'Riley is ghosting in on goal from the right but he opts to lift the ball into the middle rather than taking on the shot and a defender in red is there to intercept.
