Rob Holding is nursing a bruised knee and is a doubt for Monday’s game with West Ham United.
The centre-back returned from his ACL injurt in the September win over Nottingham Forest but hasn’t featured since the 2-0 defeat at Leicester on 9 November, his only Premier League game time of the season.
The 24-year-old has been missing from the squad for our last four games against Southampton, Norwich, Eintracht Frankfurt and Brighton.
Up to now, the weekly update from the medical team hasn’t explained his absence. This news would go some way to explain why he wasn’t selected by Unai Emery and Freddie Ljungberg.
Dani Ceballos is the only other player out injured at the moment. He’s got a hamstring problem and won’t return to training for another week or so.
