Becoming part of a small Spanish contingent at the club known as "the three amigos" alongside Jesús Seba and Isidro Díaz, he was a regular first team player for six years, the longest period of time he spent at one club. During his time there, he won the Football League Third Division and the Football League Trophy. He moved to Scottish side Motherwell, then to Walsall, before joining Swansea City in 2003. He became club captain and helped the team to win promotion to League One in 2005. He moved to Chester City in 2006, and was again chosen to be captain.

In 2007, he retired from playing to become manager of Swansea City, leading them to promotion from League One as champions. He then joined Wigan Athletic in 2009, helping the club avoid relegation for three consecutive seasons. In his fourth season Wigan were relegated, but won the FA Cup for the first time in the club's history. At the end of the 2012–13 season he left to become the manager at Everton.
