The Portland Timbers have announced the signing of Ghana U-20 National Team member and midfielder Kalif Alhassan for the remainder of the 2010 USSF Division-2 Pro League season.

Alhassan, 19, joins the Timbers after suiting up for Liberty Professionals of Ghana's GLO Premier League from 2007-10. He is scheduled to arrive in Portland and begin training with the club in early September.

"Kalif was one of the standout players from my recent scouting trip to Ghana," said Gavin Wilkinson, head coach and general manager for the Timbers. "He is a young, attack-minded player, who we think has a bright future."

Alhassan has been a member of Ghana's National Team system since 2007, playing with both the U-17 and U-20 National Teams. He was first invited to be a part of the Ghana U-20 National Team in 2008 and has participated in several camps for the U-20s, including the 2009 Youth African Championship and the 2009 FIFA U-20 World Cup. In 2008, he was also called into camp with the senior national team for the 2009 African Nations Championship.
