Danilo, just off the bench for Bojan Miovski, watches a shot deflect wide.

Thelo Aasgaard, who is also just on for Connor Barron, then whips in a corner that's glanced past the far post by Emmanuel Fernandez.

The hunger and commitment being shown from this Hearts team this afternoon has been phenomenal.

Every time they lose the ball there are three or four maroon shirts surrounding the Rangers player in possession.

We're now under way at Celtic Park.

As far as Aberdeen's concerned, it's a very recognisable back five and at times it will be a back five. Defensively they've been pretty solid for the first part of this season. They've had their blips of course.

At the other end of the park, it's not the same. It's disappointing from the point of view of actually creating opportunities and having players that look as though they can take any of the opportunities created.

Kevin Nisbet is not looking anything like his best and [Marko] Lazetic is one that, at times, looks as though he's capable and at other times he gets too involved with defenders.

That's Aberdeen's main issue - finding the back of the net.

Frankie Kent has to score, nodding a free header from yards out straight at Jack Butland following a corner.

Up the other end, a scramble at the back post ends with the ball dropping wide.

Can he take an extra touch to take himself inside the box? He's got his hands on his head.

As the second half goes on, that's the best chance for Hearts, catching Rangers when they're open.

Hearts work a counter attack perfectly, until the finish.

Claudio Braga slips through Lawrence Shankland, but his low finish towards the bottom-left corner is pushed wide by Jack Butland.

Celtic's stadium announcer pleaded with the fans to 'make some noise' while he reads out the team.

Near radio silence.

Nancy's certainly consistent, isn't he, and consistent in picking almost the same formation. The three at the back, he thinks it works, I certainly don't think it worked.

At times, it's not a back three. Against Dundee United [Kieran] Tierney was running off up the left-hand side, he did the same with [Liam] Scales in that same position when he played there in the cup final and [Anthony] Ralston at times was also trying to overlap Yang up on the right-hand side at times.

That worked OK when they had lots of the ball in the first half, second half they couldn't get out and they couldn't defend their box properly and they couldn't win the battle against Dundee United, that was evident.

He wants consistency. Let's see if they can continue the form they had in the first half into 90 minutes. If it doesn't happen, this crowd here, the anxiety, the frustration, everything, will show itself.

Djeidi Gassama completely fresh-airs an attempt at the back post then handballs in the Hearts box, to the noise of sarcastic cheers from the home fans.

James Tavernier's afternoon is over and he hands the armband to Nico Raskin.

Djeidi Gassama is on and that will surely mean another change of shape.

I was halfway down the stand celebrating.

As soon as it falls to Shankland, seven or eight yards out, you're thinking 'goal'.

It won't affect him, but he should be scoring that.

Lawrence Shankland passes up a huge chance to kill this game.

Alexandros Kyziridis drives into the left of the box and rolls the ball across to his team-mate, whose finish is just past the bottom-right corner.

He knows he should've scored.

Stephen Kingsley takes a set of studs to the top of his foot while giving away a corner, which is cleared to the edge of the box before Connor Barron drags well wide.

Rangers' first shot since the 24th minute.

Wilfried Nancy doesn't come across as a man under pressure.

As cool as you like, he was unfazed by questions of his system, his position and the fan protest going on outside.

Perhaps notably, the Celtic boss hasn't been back out the tunnel at all while his players have warmed up.

But, then again, he might just be staying cosy inside because it is right chilly at Celtic Park.

He's an unbelievable player but sometimes when Braga makes a mistake, he tries to overcompensate.

He's been holding on to the ball, losing it. He needs to settle himself down, get himself back into the game.

Michael Steinwender is fuming with Claudio Braga, who chooses not to attempt to find the right-back running up the wing and into the Rangers box.

Don't blame the Hearts defender, tbh.
