Haissem Hassan cuts inside to let fly, but the Celtic winger's shot goes high over the target.

Oooft! Almost a third for rampant Rangers as Emmanuel Fernandez just fails to touch home a flashing delivery at the front post.

Celtic are all at sea. Every time I look up, Rangers are piling forward.

Djeidi Gassama speeds forward for Rangers once again and Kieran Tierney needs to nod clear at the back post to prevent Ryan Naderi getting to the winger's cross.

Camilo Duran, now playing through the middle for Celtic, goes haring after a ball over the top, but home goalkeeper Ivor Pandur is out quickly.

This appears to be going one way only and it's Rangers' way. By a stretch.

They have dominated this and there is no sign of Celtic fightback at all.

This looks to be a massive moment in the context of the season.

Celtic go to the bench again, with old stagers James Forrest and Alex Oxlaide-Chamberlain replacing Benjamin Nygren and Kasper Hogh.

It looks as if Emmanuel Fernandez has nodded a James Penrice free-kick past Sam Johnstone, but an offside Nico Raskin got a touch.

That finish, on a first-time volley, that's not easy. The way he controls it, keeps it low, Johnstone has absolutely no chance.

The goal stands and the Rangers fans get to celebrate all over again.

Lots of booing as the VAR check goes on.

Was Ryan Naderi in an offside position?

Dan Neil drives Rangers forward and Sam Johnstone needs to make a sprawling block to deny Kim Min-Su.

The keeper spills the ball moments later, but Celtic hack it away.

I'd be putting James Forrest on the pitch right away.

It looks as if Duran doesn't want to come out onto this left hand side.

Celtic are getting forward a bit more than they were in the first half but nothing is sticking for striker Kasper Hogh.

Camilo Duran threatens to break into the box for Celtic but Dujon Sterling calmly steps in to thwart the danger.

No one can get the ball under control near the Celtic penalty area before it drops to Kim Min-Su, who powers a shot on target.

Sam Johnstone does well to push it away to safety.

Haissem Hassan looks lively already and now Olwethu Makhanya is on a booking for bringing him down on the touchline.

Here we go for the second half.

Haissem Hassan is on for Celtic, replacing Sebastian Tounekti.

The Egypt winger will play on the right, with Camilo Duran switching to the left.

Derek McInnes has got his tactics spot on, I think he's caught Celtic massively off guard.

I think the second half is going to be completely different. I'm expecting a completely different Celtic side.

There's only one goal in it, that's nothing.
