Zak Whitbread--American-born, 18 year old defender, who has lived in England for some time. Obviously, he's a youth player at Liverpool. He's played a bit with US youth teams, but is not cap-tied.
Beyond this, none of us knows very much about Zak. His father, Barry, was a low-level English professional who went on to become a coach. When Zak was accepted by Liverpool at age 15-16, Barry resigned from Singapore's head position to move to England with him. Incidentally, Barry did quite well in Singapore, winning the Southeast Asian championship against some much more populous countries.
