"Rangers just snapping in to challenges. Celtic, on occasions, just look like they don't want to play it short. They're a little frightened of the pressure Rangers are applying."

Celtic midfielder Callum McGregor, wide on the right, has a chance to emulate James Tavernier from a free kick.

However, McGregor's effort has more chance of taking out a fan's pie & bovril behind the goal than worrying Wes Foderingham.

Rueful shake of the head from McGregor.

Celtic are coughing up possession as quickly as they receive it. Neil Lennon's side have yet to settle into this game, or get any kind of service up to an isolated Odsonne Edouard.

In sharp contrast, Rangers are buzzing in the Sunday sunshine with Kent and Defoe threatening.

Thumbs up for excellent finish, thumbs down for poor defending. We know what Lenny thinks...

Rangers try to outfox Celtic with a clever short corner but Scott Arfield's pass into the path of the galloping Ryan Kent is too heavy and it's out for a goal kick.

Bill E. Kaunelli: Defoe's dive will be one for the Compliance Officer

Referee Kevin Clancy tries to restore calm in the May sunshine as an over zealous Scott Arfield receives a stern talking to for a sliding challenge on Celtic captain Scott Brown.

Not sure what the eagle-eyed whistler is saying to Arfield but there's enough arm movements there for a Zumba class.

No booking, and we're back under way with Rangers still a goal to the good...

"I think that's a booking. He has dived and he's tried to deceive the referee. That should be a yellow card for Defoe.

"Jermain Defoe takes a touch here. He just clips it. Kristoffer Ajer then comes in. No, that's not a penalty."

"I don't think Neil Lennon will be overly concerned with the start. He'll will know that in these types of games it takes time for your team to settle."

Jermain Defoe takes a tumble in the box under the close attentions of Kristoffer Ajer. Replays show no contact - "that's never a penalty," says BBC Sportsound pundit Neil McCann.

The veteran striker can perhaps count himself lucky for not being booked by referee Kevin Clancy.

Jermain Defoe, preferred instead of Alfredo Morelos, tests Scott Bain with a fierce drive. The Celtic keeper parries and collects at the second attempt.

Seconds later Oliver Burke blazes an effort high and wide - pretty much summing up Celtic's opening quarter.

After suffering that early bloody nose in the form of James Tavernier's goal, Celtic enjoy their longest spell of possession. However, Rangers heels are snapping at everyone in green and white.

Wes Foderingham hasn't been called into question yet.

Jonny Hayes sends a cross into the box but it drifts out for a goal kick. Neil Lennon, arms folded, stares downward in his technical area.

"The pressure from Rangers is just relentless. What Rangers have this season - and I think Glen Kamara has made a big difference - is really good players that can keep the ball."

Early, frantic days, but a certain Rangers captain may do well here...

PLAYER RATER

Ryan Kent looks in the mood for Rangers. The winger launches another attack but Celtic, somewhat unconvincingly, snuff out the danger.

You'd be forgiven for thinking Celtic thought kick off was 12:30.

James Tavernier celebrates his opener after just two minutes, with the Celtic defence all-at-sea.

Rangers, a goal to the good and enjoying the lionshare of possession, have the ball through Scott Arfield and he dinks it wide for James Tavernier.

The Rangers skipper whips a cross in but Scott Bain gathers.

Celtic winger Jonny Hayes fouls James Tavernier, this time wide on the right, as the hosts seek to double their lead. However, the visitors clear their lines from the set piece.

Rangers in the ascendancy in the opening five minutes, with Celtic looking far from convincing.
