I doubt it'll set him back too much. He's got at least five years until he's a first-team regular at Arsenal, so a little injury isn't really going to affect that much.
Just passing on what i know.. i hear he did bit of running on th etouch line, so i reckon its just a knock!
I am at the match and he did get up and play for a bit after a bad challenge but walked off 2 minutes from halftime. His workrate , skill and attitude could not be faulted. Hopefully, nothing serious.
agreed, although it is only 1 mistake but still think barts not ready for the no1 yet. . . maybe the odd game here and there?
