[1] In the summer of 1995, he was part of a group of players dubbed "The Three Amigos" – which also included his compatriots Roberto Martínez and Jesús Seba – who were brought to Wigan Athletic by club chairman Dave Whelan;[2] he helped the team win the Third Division title two years later, with the player contributing six goals in 35 matches.
[3] Unable to agree a new deal, Díaz left the club by mutual consent in July 1997[4] and signed for Wolverhampton Wanderers.
He played one game for the latter, a 3–0 away defeat against Oxford United,[5] before returning to Springfield Park later that year; his second spell with Wigan was not as successful, appearing just three times in the league before moving to Rochdale at the end of the season.
Díaz spent the following seven years in Portugal and its Segunda Liga, appearing and scoring regularly for both Leça (one season) and Chaves (six, where former Zaragoza and Wigan teammate Seba had already played).
[9] Díaz retired from football at the age of 40, after playing one and a half seasons with Laredo in division four and one with Castro in the same league.
