Freddy Adu's future is again in limbo after his tryout at Swiss club Sion failed.
Sion was on the lookout for players because a one-year FIFA transfer ban will begin in January but it said Adu did not fit in with its plans.
"I know I'm going to be praying," Adu wrote on his Twitter account. "Until then I will be incognito."
Since joining Benfica in 2007, he has been loaned out to three teams, Monaco, Belenenses and Aris, but has failed to live up to expectations.
