That's Nicolas Kuhn's last involvement.

He comes off for James Forrest, who is making his 500th appearance for Celtic.

The veteran winger gets a huge ovation.

And another.

Nicolas Kuhn body checks Jefte on the left as the full-back attempts to break clear.

Lovely from Kyogo to spin away from John Souttar, but his pass is overhit and the attack breaks down.

Welcome to the Old Firm derby, Arne Engels.

Tom Lawrence bodies the new Celtic midfielder and takes a card for it.

Tom Lawrence sends Nicolas Kuhn flying after making a block.

Again, hard but fair.

Robin Propper almost finds his own net, steering an Alistair Johnston cross to the near post.

Jack Butland gets down well.

Another chance for Ross McCausland that he has to do better with.

Jefte's low ball from the left finds the winger, who opens his foot up but doesn't connect cleanly.

Here comes Arne Engels for his Celtic debut.

He replaces Paulo Bernardo in midfield.

Let's see what he's all about, then.

James Tavernier bends in a beauty of a ball but Ross McCausland's finish nearly clears the ground.

Bang.

Cameron Carter-Vickers smashes Cyriel Dessers with a hard but fair challenge from behind.

Ouch.

Kyogo should be scoring that.

That should be game, set and match.

Rangers lose the ball so cheaply in the middle of the park and Kyogo gets put behind.

He attempts to dink Jack Butland but it's the wrong side of the near post.

Second Rangers switch sees Mohamed Diomande make way for Tom Lawrence.

Celtic fans are annoyed their team can't play advantage after a foul, then they get on referee John Beaton's back again as he doesn't allow a quick free-kick.

In it comes eventually from Paulo Bernardo and James Tavernier heads behind.

Like the first half, it's been a bright start from Rangers.

John Souttar heads off the back post from the following corner.

The whistle then goes as the ball had already gone out.

That was a good chance for Rangers.

Souttar does everything right but it's a great block from Scales.

Cyriel Dessers gets in the way of a Robin Propper header then Liam Scales blocks what would have been a certain John Souttar goal.

Rangers probing.

Daizen Maeda wins another header at the front post but again nobody is there at the back stick to finish it.
