The American youngster is hoping he will get the chance to prove himself at the Estadio da Luz....
The United States international, who had his first training session of the pre-season with Benfica today, does not know yet whether he will be part of the plans of coach Jorge Jesus, but he is hoping to impress his new boss.
"I will be training with Benfica tomorrow [today]," the player said on his Twitter page. "I am excited and cannot wait to start training.
"I am not 100 per cent sure if I am staying or not, I want to but you never know."
Adu, 20, signed for Benfica from Real Salt Lake in the summer of 2007 for a fee in the region of €1.5 million.
