That's one of the best performances I've seen from a Celtic team at Ibrox in years.
Maeda is in Tavernier's head. Tavernier is in the right position but he switches off, and Maeda doesn't give up on it (for the opening goal).
From then on, it's been an annihilation. Celtic have been magnificent.

A huge half-time team-talk ahead for Philippe Clement.
Celtic deservedly ahead by two and there are some very, very unhappy Rangers fans around me right now.
The visitors are in control at Ibrox.
Celtic have been so much sharper than Rangers in every facet of play, buoyed by a Daizen Maeda goal after just 21 seconds.
Matt O'Riley added a penalty and the margin could be greater, with the home defence all over the place.

Huge save from Joe Hart.
Fabio Silva looks like he's going to send it under him but Hart spreads himself.
A big moment at the end of this first half.

How many times have we seen that save from Joe Hart?
Fabio Silva is through one-on-one but the Celtic keeper spreads himself to make a sprawling stop.

The difference between Rangers' front line closing Celtic and Celtic's front line closing Rangers is night and day.
Straight from kick-off, Celtic are hounding them.

Rangers have lost it, from a composure point of view. They can't handle their own crowd getting on top of them, they can't handle the conditions, and they can't handle Celtic's pressure.

As Rangers win a corner, that is pushed over by Joe Hart, John Souttar leaves the field with a nasty cut on his head.

Fabio Silva is down in a heap after a collision with Alistair Johnston. Referee John Beaton produces a yellow card for the Celtic defender long after the fact.
"Amateur dramatics" from Silva, according to Sky pundit Kenny Miller.

There's going to need to be a few changes at half-time from Philippe Clement.

Former Celtic goalkeeper on BBC Sportsound
Celtic deserve it. They've created chances, dominated the game, bullied Rangers in midfield. That was always going to be a critical area. They've had composure on the ball, passed it around.
Rangers haven't got close enough, they've been nervy.
Matt O'Riley (pen)
Dinked right down the middle.
Nerves of steel from Matt O'Riley.
Rangers 0-1 Celtic
Complete silence in the stadium as John Beaton points to the penalty spot.
Rangers 0-1 Celtic
John Beaton is off to the monitor. The Referee has been asked to check out the ball crashing against the elbow of Connor Goldson as Rangers were defending a corner.

Right on cue, Jack Butland steps up in front of the England manager to make a huge save.
Maeda shows such great ability there and O'Riley does everything right, putting that header in the top corner. But it's a great save.
