The hopeful but disappointing Adu is not needed by the Swiss club © EuroFootball.com

A few years ago, Freddy Adu, considered one of the most promising football players in the world, was deemed unnecessary for Switzerland's "Sion" club.

Last season, the American, who belonged to Lisbon's "Benfica" team, was loaned to Salonika's "Aris", but the Greeks did not want to extend the loan agreement.

Therefore, Adu went to Switzerland, but after a week of training with "Sion", he did not impress the coaches of this team.

Having signed a contract with "Benfica", the American footballer was previously loaned to Portugal's "Belenenses" and France's "Monaco".
