Why? It doesn't leave him here forever. Maybe two more years and he gets transferred back to Europe. Certainly better than languishing on Benfica's reserve team.
It's true that he's young and has time to develop more here in MLS and then go back to europe. I think it's good for us and probably the right decision for him in the long run. I was just surprised that he would make the decision to do so considering every article that's been written about him in the past year has talked about his european aspirations.
i hope this is true and we do get him and he is even better for us this year than last year (except for the playoff game where he was just... bad).
