Mikel Arteta says Piero Hincapié and Martin Zubimendi will miss Arsenal's Champions League match against Lille after injuries in a post-Leeds training session, the club reported on 12 October. Further scans are needed to establish their absence, with Hincapié's problem appearing more serious pending assessment. William Saliba is doing individual work on grass but remains weeks from a potential return. No firm comeback date has been established for the three players.
