Born in
Concepción del Uruguay, Chamot began his career with
Rosario Central in his native Argentina, and then moved to Italy, where he played for
Pisa (1990–93),
Foggia (1993–94) and
Lazio (1994–98). His spell at Lazio cemented him as one of the top full-backs in the
Serie A; during his last season with the Roman club, he won the
1997–98 Coppa Italia. While playing for Lazio, he deliberately shook referee
Pierluigi Collina's hand too firmly post match, and earned a one-game ban for dissent. Chamot then moved to Spain, where he spent one and a half seasons with
Atlético Madrid, before returning to Italy (in the January 2000 transfer window) in order to join giants
A.C. Milan, for whom he played until 2003, winning the
2002–03 UEFA Champions League and the
2002–03 Coppa Italia. He left Milan during the summer of 2003 (by that time he had lost his place in the starting eleven) and signed for Spanish side
Leganés. After an injury-plagued season there, Chamot returned to Argentina to spend the final years of his career (2004–06) with Rosario Central, the club where he had started as a professional footballer; again, however, he was troubled by injuries, and announced his retirement at the end of 2006. == International career ==
