If you're a Celtic supporter, you're a little bit frustrated and a little bit nervous that you could end up losing the game after all those chances.

For Rangers to be back in the game is quite incredible.

Exactly what Danny Rohl would have sought at half-time and suddenly it's the away support in full voice.

All the questions have returned for Wilfried Nancy. Celtic deserve to be ahead but aren't and now you wonder if things may get worse as they often have in his short tenure.

This is going to end up like a basketball game. You can feel it.

Yang Hyun-jun rises to meet the free-kick and the winger's header is turned over the crossbar by goalkeeper Jack Butland.

It swinging from end to end now.

Half chances for both sides.

Djeidi Gassama is in the book for a foul that hands Celtic a free-kick outside the penalty box.

Clever little pass from McCowan.

Butland gambles and it's a big save.

Great chance for Celtic to restore the lead.

Daizen Maeda is through on goal, but the winger's prodded effort is blocked superbly by goalkeeper Jack Butland.

You felt it had been coming. Rangers had just got a little bit more possession, it was really good play from Raskin.

I'm surprised that it got beyond the near post.

Celtic aren't fully switched on and Chermiti has the simplest of tap-ins.

He has to get going again, Mo Diomande. He's a really good player. He's got a habit of taking too many touches. He'll certainly get forward from that position.

Celtic already have a corner and, when the ball drops to Callum McGregor, the home captain fires a low drive a few feet wide.

I don't think Rangers can be as bad again. If Celtic don't kill this, there's going to be an opportunity.

The attacking subs will probably come a little bit later in the game.

Celtic get the second half under way.

Celtic and Rangers have both won 172 games against each other, with 104 drawn.

Unless something significant changes, Celtic are heading for win number 173.

Rangers have brought on Mohamed Diomande for Thelo Aasgaard in midfield.

The Norwegian was anonymous in the first half after being booked early on.

This is going to be a big test for Celtic in the second half.

I could see Rangers coming into the game. They have to do something to rectify what happened in the first half.

If Celtic get a second goal then it's a different story. If they don't, there will be pressure and the defensive qualities of the side will be tested.

Yang has been fantastic in the first half.

A fantastic goal and he's been Celtic's best player.

Celtic's goal came from one of their 11 shots in an intense opening period.

Six of those efforts have come from inside the Rangers penalty box.

Kris Boyd
Former Rangers striker on Sky Sports

That goal epitomises Rangers' first half. They've been all over the place.

They've been lucky Celtic don't have a number nine.

If you need a graphic to highlight the influence of Hyun-jun Yang in that first half, here it is.

Almost half of Celtic's attacking play has come down their right-hand side - 44% to be exact.

It also shows, as pundit Michael Stewart has been saying on Sportsound, Rangers have been "awful" down their left.
