At the 2012 Olympics, which former England left-back managed the Great Britain men's football team?

Shame we havnt had a Great Britain Olypic Football team since as i feel with a wealth of young talent we'd have a chance of a medal. Not sure how many over 21 players you're allowed but remember Ryan Giggs & Craig Bellemey were two of the over age players to represent GB in 2012.

Did he improve Longford?
