Freddy Adu, Headed to Benefica?

The rumors around Freddy Adu leaving Major League Soccer for Europe have been swirling on and off since the off-season if not the last couple of years. Recently the chatter has stepped up again and it would seem from the article below there is something to Adu being linked with the Portugese side Benefica. Will it happen? If so, I'd expect RSLFM to give us the best insight on it. Salt Lake Tribune :

Sources confirmed media reports that Adu is most likely headed to Benfica in Portugal, in part because of how difficult it would be for him to obtain a work permit to play for either of the other two teams most interested in him, Celtic FC in Scotland or Tottenham Hotspur in England.

However, Adu and his agent still must work out a transfer fee with Major League Soccer - the league owns the contracts of all its players - in addition to the details of a personal contract with any potential employer. Media reports have said the league wants $7.5 million for the rights to Adu, a price that might be viewed as too steep for a player who, despite his star turn at the recent Under-20 World Cup, has done little for RSL.
