Mikel Arteta couldn't rule out the possibility that William Saliba would miss the rest of the campaign as he battles injury.
The Arsenal centre-half has been a leading light since becoming a first-team regular but has been missing in recent weeks due to a back issue he sustained in the Europa League defeat to Sporting Lisbon. Rob Holding has filled in alongside Gabriel since, but the Gunners have failed to keep a clean sheet in that time.
Arsenal are heading into the final weeks of the season with a charging Manchester City closing in and Saliba's return would be a welcome boost. Arteta though admitted he wasn't ready to return and couldn't guarantee he would feature again this term.
