Lopez, who played for Jeanne d'Arc at youth level, started his senior career with
Pau in 1979, remaining until 1982 when he agreed to join
Division 2 outfit
Châteauroux. Lopez completed a return to Pau a year later, prior to signing for
Division 1 side
Bordeaux. The club won the title in his sole season there, qualifying for the
1985–86 European Cup. However, Lopez departed Bordeaux at the beginning of 1985–86 to play in Division 2 for
Mulhouse. His stay lasted twelve months, preceding a period with
Thonon between 1986 and 1987. In the latter year, Lopez rejoined former team Pau for a third time. Five years later, he retired from football. ==Non-playing career==
