Shame to see AOC go, but thanks for the cash, the add-ons and the sell-on fee.
Personally I don't think the move is the right one for him. He would have got regular first team football at Saints, which would have only improved his already considerable talent. Heck, even a move to the likes of Blackburn, Stoke or Aston Villa would have probably given him more first team experience than he's going to get at Arsenal for the next few years.
Still that yet another wunderkind moving off the academy line to join Bale and Walcott and Bridge.... Hell, even our record for producing second "regular footballers" like Surman, Baird and Dyer isn't a bad one. I suspect we'll be having the same discussion about James Ward-Prowse in a couple of years.
So, anyway, thanks for the cash. Don't waste his potential like you did Theo, cos I want to see the boy in an England shirt some day.
