Which American Should I Get Next? (FIFA 12)

In my second year as manager of Everton, currently fifth in the EPL and heading into the final matches of group stage in Champions League action (finished third in EPL in first season).

The main goal I have is to eventually make Everton a five-star club with at least one FA Cup, Carling Cup, EPL crown, and Champions League title before I call it quits.

My second goal is to pump as many Americans as I can into the team. Right now I have Landon Donovan, Freddy Adu (sub), Omar Gonzalez (sub), and (of course) Tim Howard on the team right now.

Heading into the winter transfer period, who's an American star that I can go out and get?

(FCD won't sell me Shea for anything...they don't have enough midfielders on the squad to allow them to sell him to me.)

Oh, and here's my current starting XII:

ST: Saha
LW: Hulk (Sold off a bunch of veterans in the first season to buy him off...currently leads EPL in goals)
RW: Donovan
CAM: Tshabalala (South African star, just a personal favorite of mine) or Osman
CDM: Fellaini/Ramires (former Chelsea man)
LB: Baines
CB: Distin/Heitinga (moved him from CDM)
RB: Neville
GK: Howard
