(Reuters) - Arsenal manager Mikel Arteta said it hurt him to leave defender William Saliba out of his Europa League squad, a decision that looks to have backfired with the club face mounting injury problems at the centre back position.
Saliba and Sokratis Papastathopoulos were not registered for the competition, and with Rob Holding, Calum Chambers, Pablo Mari and David Luiz all injured Arteta is left with Shkodran Mustafi and Gabriel Magalhaes as his only centre backs for Thursday's match against Irish side Dundalk.
