Patrick Roberts is expected to play his first game of the year tomorrow night against Dundee while Marvin Compper could also make his debut for the Parkhead side.

Roberts came through a development game unscathed last Friday night while Compper has shaken off a calf injury in each leg since his arrival at the club in January.

However, Celtic manager Brendan Rodgers has revealed that Kristoffer Ajer is a doubt for tomorrow night’s game against Neil McCann's side at Celtic Park.

Ajer was left with a heavily bandaged head after clashing with Jozo Simunovic in the 2-0 win over Aberdeen at Pittodrie on Sunday afternoon. Ajer managed to see the game out but with a swollen eye may not make it in time for tomorrow's clash.

Mikael Lustig is suspended for the game but there is an alleviation in the injury issues with Tom Rogic getting a few games under his belt with Compper and Roberts set to follow.

“Kris has suffered from the head knock and we’ll need to see how he is in the next 24 hours,” said the Celtic manager.

“He ended up with his head all bandaged up like Rab C. Nesbitt! The problem is above his eye. He obviously needed stitched up on the pitch but after the game his eye fully closed.

“It was probably hard for Bobby Madden to see the clash at the time and if he had he would have stopped the game.

“Patrick will be back available for Dundee. Marvin Compper as well. Patrick played in the development game last week and has been training for a few weeks.

“It’s great to have him back. You see his quality and his creativity, he’s fantastic to have back.

“We need to be careful and manage him, without holding the player back. He’s worked very hard in the last few weeks.

“It’s a bit like we seen with Tom Rogic. When you are out for a while you need eased back in with minutes here and there. It will need to be the same with Pat.

“Marvin had the initial knock on his calf in Dubai then he was getting back fit and he felt the tightness on the other side.

“He’s been training for a little while now so we will see.”

Rodgers also explained that while he was consulted by Scott Brown prior to the decision to step down from international football, the final call came from the player himself.

“We spoke briefly about it," said Rodgers. "It’s been several months since he last played for Scotland but this choice was always going to be down to Scott and now we can move forward.

“I’ve always got an opinion on it but ultimately it had to be down to him.

“He spoke to Alex and I spoke to Alex as well, so they are in agreement and at least now they can move forward together and Scott can celebrate a great history of playing for Scotland."
