Gifted youngster Alex Cooper was a target for several clubs

The 16-year-old winger, who has won caps for Scotland at junior level and was a target for Chelsea, is the son of former Aberdeen star Neale Cooper.

Cooper has signed a contract with the Anfield club until 2011.

His father Neale, said: "He could have gone to one or two other clubs but he just loved the way he was treated by Liverpool when he was there."
