Roma would be the best. Maicon is on the downswing and Italy is a better league for Yedlin than England.
Maicon was very good for them last year. Still think it's hard for him to get regular playing time there
I assume US players are looked upon much like a white running back is in football? Doesn't matter how good you are, you are American, thus you must suck.
They're usually looked on as good guys to have on your team, but not game changers. The don't quit attitude and effort that usually comes with US players is appreciated.
I know that Bradley was quite appreciated in Italy, things like his diligence in learning Italian, and his play there as well. Roma just acquired a couple of better players.
Green made the first team at FC Bayern Munich: http://www.fcbayern.de/en/teams/first-team/ That's a pretty big deal.
