Kaka: They can't have Messi or Ronaldo since they're signed to PES. Rooney plays for the most hated team in the world and (from a marketing standpoint) is already balding and hes not even 25. As far as big, marketable names go, Id say Kaka right behind the aforementioned. Not what he used to be, but he's better than Ronaldinho lol.
Vela: They usually select young players who are about to break out. Velas been primed to do that for a while now. After watching a couple Arsenal games, Im not too impressed with Chamkah, so i think he should get some decent time this year.
