Greg Taylor
Rangers are caught napping at a free-kick, which is played out to Callum McGregor and the Celtic captain slides in a pass to Greg Taylor after shaping to shoot.
Taylor does have a crack and his effort clips defender Calvin Bassey and the deflection takes the ball away from Jon McLaughlin and into the corner of the net.

Quote MessageRoofe is a lucky man to be on the pitch. Everybody knew what he was going to do, the referee knew it too. He's lucky it's just a yellow card because Maeda was gone. He comes from behind and takes him down.

Quote MessageThe fact that it's 0-0 is a bit of a triumph for Celtic. You have to take your hat off to Rangers, given the exertions of Thursday night. The game has been played to their tempo. They're up for a fight, up for a battle. They've nullified the Celtic threat almost completely.

Quote MessageI think Celtic have struggled throughout. Tactically, Rangers have been superb. Every time it goes to a Celtic player, Rangers are all over them. They're playing a high line at the back and they are hunting down the Celtic players.

Celtic have not really been at it so far, with Rangers goalkeeper Jon McLaughlin a virtual spectator.
Will Ange Postecoglou be thinking about bringing Kyogo Furuhashi on for the second half?
A breathless first-half comes to a close with Joe Aribo glancing an unconvincing header wide from Scott Wright's cross.
Rangers have been on top and went closest to a goal when John Lundstram cracked the post with a sweetly-hit shot.
Kemar Roofe had earlier threatened with a drilled effort that flew just wide.

Thomas Duncan
BBC Scotland at Hampden
Aaron Ramsey knew his afternoon was done as soon as he hit the deck. It's a shame for the Wales midfielder as he's had a good game.
Can Scott Wright make the same impact?
Celtic 0-0 Rangers
Aaron Ramsey has come off worse in that tangle with Cameron Carter-Vickers and the on-loan Rangers midfielder can't continue.
Scott Wright replaces the man from Juventus.

Quote MessageThis game has been exceptional in terms of the pace it's played at. Joe Hart's just not getting John Lundstram's shot. Then Celtic just go and attack Rangers.
