Arsenal concern as Saliba out of Leeds clash

Arsenal defender William Saliba is out of their clash with Leeds United.

Saliba is set to be ruled out due to a back injury.

The Frenchman was forced off during their Sporting CP Europa League defeat a fortnight ago and hasn't been able to return to training since.

Saliba had started all but one of Arsenal's Premier League games this season. He missed the 4-1 win against Crystal Palace and also pulled out of the France squad.

Due to the back injury, Arsenal cannot put a firm date on Saliba's return.
