Ridgewell was not O´Leary´s first choice at the start of the 2005-06 season, but injuries to the likes of Martin Laursen, Mark Delaney and skipper Olof Mellberg meant he started 33 games. The reward for the England Under-21 player is a contract until the summer of 2009.
"Liam has stood up and has been counted," O´Leary told PA Sport. "All of last season he was playing with different partners and did really well."
