Yeah it does, that's a new contract negotiated in January, isn't it? Wilshere was fantastic for the preceding 5 months and got a pay-rise commensurate with his rise in squad status. AOC is an unproven youngster so whilst he's probably on better wages than the equivalent player at a different club it won't be enough to break the wage structure which is, allegedly, what was holding up our summer. I don't say I particularly believe it, it's easy enough for someone to make up any old bollocks but that transfer seems to support it.
I agree with you that the squad still needs work, although I'd add an AM to that as we're losing one of the most creative player in the world and the guy we groomed as his replacement, if he's a goal-scorer we might not need another striker but with Chamakh's worrying form it wouldn't hurt.
