Freddy Adu will undergo his fifth loan deal since joining Portuguese club Benfica back in 2007.

The 21-year old, who promised so much earlier in his career, has struggled to establish himself in Europe and will now find himself in Turkey's second division with Caykur Rizespor.

Adu was training with German 2.Bundesliga club FC Ingolstadt but has linked up with Turkish outfit for the next six months. His deal with Benfica expires in summer 2012 and he will be hoping to secure a contract somewhere prior to that time.

Caykur Rizespor currently sit third on the Bank Asya 1. Lig table.
