The league leaders "don't know the extent" of the issue yet but the defender was forced off 30 minutes into their win against Wolves.

Saturday’s late game pits top against bottom in the Premier League.

The Gunners made their clash with Wolves far more grueling than it needed to be, which doesn't bode well for their title aspirations.

The big news for Arsenal is that William Saliba is back in the starting line-up for the Gunners. The centre back missed five games for the Gunners but is back for this match. There's also a start for Jurrien Timber who was not in the squad for the game away at Club Brugge in the Champions League.
