Matthias Pogba is coming on for the hosts as Kris Doolan trots off. Can they get a few decent crosses fired into the big striker with the famous wee brother?

David Amoo on the turn near the penalty spot but Celtic captain Scott Brown manages to get a leg out and the ball spins over for a Partick corner.

Kiernan Tierney pounces on a slack pass from Abdul Osman to set up a swift Celtic attack. The teenager centres for Kris Commons but the midfielder takes too long to get the ball under control and he's eventually crowded out by a cluster of defenders.

A shake of the hips from Steven Lawless inside the Celtic penalty area creates space for a shot but his rising effort is off target.

We're up and running again...

It's been an open, entertaining game so far, although Thistle fans may be worried about how much space the visitors have been enjoying in attack. Will we get more of the same in the second half?

Celtic are good value for their lead since they enjoyed the bulk of pressure in the first half but Thistle are still in it and had a few sights of Craig Gordon's goal, the keeper making impressive saves to deny Kris Doolan and Liam Lindsay.

That's 35 goals for Leigh Griffiths. Surely he will be given a chance to show what he can do for Scotland in this month's friendly against Denmark.

Alan Archibald must have been readying his half-time address, satisfied that his side had been holding on and causing a few problems of their own but the Jags boss will now be furious that Scotland's top-scorer was allowed two touches in a busy goalmouth to open the scoring.

With the home side down to 10 men while Abdul Osman receives some injury treatment, Celtic keep coming as Erik Sviatchenko gets his head to a corner, with Sean Welsh nodding it clear off the line.

Nir Bitton then thunders in a shot from distance, with the ball flashing very close to the top corner.

Tomas Cerny is having a busy spell as he dives full length to push away a bouncing, angled strike from Leigh Griffiths.

Tomas Cerny is under pressure from an in-swinging Kris Commons corner, eventually flapping the ball away. Another corner, and the home defence is posted missing as Mikael Lustig powers a header wide. 

A comfortable save for Craig Gordon this time as Jags' left-back Callum Booth tries his luck with a strike from distance.

Another Thistle caution, with Gary Miller booked for crunching into Gary Mackay-Steven before Kris Commons hammers a shot straight at home keeper Tomas Cerny.

Best chance so far for Partick as Kris Doolan wriggles through a couple of challenges but he can't poke his shot past Craig Gordon, who was off his line swiftly to make a good blocking save.
