Unfortunately it probably will dictate it. This one change is a pretty clear example of why we're not quite in the same bracket as the current top 6, we don't have the depth. Starting 11 - brilliant. But if we start losing members of that 11, which will happen over the season, we don't have real quality to step in. I'm not saying we need equals on the bench, but if we're honest -as good a bloke as he is - Jos is not a PL footballer, so it's not ideal that we're having to rely on him.
I hope he goes out there, scores a goal and proves me wrong, but I just get the feeling that Arsenals attack will run rings around him.
