Arsene Wenger has revealed that Laurent Koscielny is a doubt for tomorrow night’s game with Sunderland having succumbed to flu.

The French international is unlikely to be risked in the circumstances meaning Gabriel could get a run out for the first time since the FA Cup semi-final against Reading.

“We have an uncertainty about Koscielny,” Wenger told his pre-game press conference. “He has the flu. I will know more after training because yesterday was a recovery day.”

The boss also confirmed that Matthew Debuchy is still not fit to return, although he could return to full training on Friday, and that Alex Oxlade-Chamberlain and Danny Welbeck will also be short for the visit Dick Advocaat’s relegation-threatened Black Cats.
