Good call.
I think he'll join on loan, as he wants to play for England and Cappello is constantly attending matches in the PL, so it's senseless to be in LA in the close season when there's England games soon.
Think Beckham being decked out in Arsenal kit is the player's way of paying for them letting him use their facilities and train with the first team squad. The additional revenue, profile raising, etc will more than cover the 'expense/burden' of having him train there.
Exactly. The fact he has Arse kit on is no indication to anything. When Adu trained with ManU he was all kited out.
