Well, why not? What would he be doing in Milan? He's out for the rest of the season, there's no reason he should stay in Milan instead of L.A. Plus, his family is in the States.
his season is done, he was only gonna be wit us till June anyways, its nice to see him at the game tho. He really does care about the teams he plays for. He is owned by the Galaxy and now lives in LA primarily i believe. Theres no reason for him to be at Milan anymore, hopefully he gets a speedy recovery and possibly gets a chance at ending International career at 2012 Euros..
