I have a Diaby theory, hear me out. If Abou Diaby plays as the deepest midfielder rather than his usual box to box then Arsène is grooming away in the hope that he can stay fit. The only possible available spot in our first team would be Arteta's role, right? So gradually bringing him back slowly and playing him as the defensive midfielder when Flamini and potentially Coquelin are on the pitch tells me that Arsène is planning something. If he plays box to box then maybe, just maybe Abou is playing out his final few months with us. We know how much Arsène loves a bit of Abou (and rightly so in my opinion) so I wouldn't be so sure.
