"Marvin has a problem with his abductor, so we'll see how that is, but it's highly unlikely he'll be available".

Craigan was blown away by Celtic's display on Wednesday, despite the fact Celtic had to deal with a red card to Jozo Simunovic in the 11th minute after a high tackle. "I thought the referee could have kept him on the pitch and given him a warning".

"He's as fit as he has been at this stage of the season, so we are hoping it is just a tightness and that he'll be okay".
"With Mika [Lustig] it's a possibility but we have to respect he's been at the World Cup and played a long season, when he comes back he won't be fit and it'll take a couple of weeks to get up to speed".
"The ball was popped back at him quickly and he's raised his boot which has caught their player".

Moussa Dembele scored twice inside the first 20 minutes, either side of Celtic centre-back Jozo Simunovic's dismissal for a high challenge on Jefferson Reis. We weren't flustered. We still tried to attack the game.
"But it is a tie we look forward to. They coped very well".
