[1] Pérez made his Sunderland debut, aged 29 on 19 October 1996, as a substitute for Tony Coton, in a 3–0 away defeat against Southampton.
At Newcastle United, Pérez was fourth-choice behind Steve Harper, Shay Given and John Karelse; he never made a competitive start for the Magpies and after being loaned to various clubs throughout his 21-month spell on Tyneside, he was granted a free transfer to Cambridge United in July 2000, reportedly taking a 95% pay cut to do so.
[3][4] Pérez was released by Cambridge at the end of the 2002–03 season, before joining Enfield in October 2002,[5] and then Stevenage Borough in February 2003,[6] after a short stint at Chelmsford City.
[7] He was a regular for Stevenage until in March 2004 (being voted Player of the Year), he broke his leg playing in a league match against Barnet.
On leaving Stevenage, Perez and his family moved back to France where he had spells coaching at FC PHA Chusclan Laudun and SO Cassis Carnoux.
