Corner to City as Kolo Toure does well to nod the ball clear from under his crossbar.

We're halfway through three minutes of stoppage time...

Suddenly space opens up for Ilkay Gundogan after another jinking run from Raheem Sterling. The City midfielder has a pop and the shot deflects off Erik Sviatchenko meaning Craig Gordon needs to readjust quickly to bat the ball over the crossbar.

What was I saying about Scott Brown struggling? The captain grits his teeth, digs deep, and throws himself in front of a Raheem Sterling shot as City camp on the edge of the Celtic box.

You're so proud of both sides, wanting to go for the win. It would be slightly unfair if City do get it, Celtic probably just deserve a draw.

Celtic might have been better removing captain Scott Brown there since the midfielder is struggling to recover from a robust Fernandinho challenge and isn't moving very well.

Celtic make their final change. And it's a bold one.

Holding midfielder Nir Bitton is off and striker Leigh Griffiths in on for the closing stages.

Raheem Sterling bundles through a couple of challenges and the ball falls to City team-mate Fernandinho, who decides to have a lash from 25 yards, with his rising shot not missing by much.

Moussa Dembele has put in an incredible shift for Celtic. The Frenchman has scored twice and done a power of running up front on his own. Celtic Park erupts in approval as he hares back deep into his own half to dispossess Pablo Zabaleta.

Here comes Patrick Roberts for Celtic. James Forrest is the man making way. What price on the Manchester City loanee doing a number on his parent club?

Celtic have been absolutely superb tonight, way beyond what we have seen from them in the last four to five years. It has been brilliant so far but they are just starting to a look a bit fatigued. I would like to see another substitution for Celtic. The tempo has definitely dropped slightly."

Defensive anchorman Fernando is on for Nolito. Is that City shoring up? I'm not sure that's the Pep Guardiola way.

A defensive reshuffle for City as Gael Clichy makes way for John Stones. That will see Aleksandar Kolarov move to his more accustomed left-back role. The Serbia international has had a bit of a 'mare in the middle.

The Celtic fans pick up the noise levels again in a bid to lift their team for the final 20 minutes.

You know the game couldn't go at the same pace that it did in the first half. Celtic are the team that are wilting that little bit more.

Neil Lennon
Hibernian manager on Radio Scotland

"The Manchester City defence has looked like a bag of washing tonight. They are relying on three or four players to try and win them the game."

The visitors are turning the screw now. Celtic just can't get out of their own half.
