Career
He moved to France in 2002, spending five seasons with Football Club Nantes before to become a mainstay at Toulouse Football Club, where he played from 2007 to 2011. In June 2011 he accepted to join Serie A club Palermo on a free transfer. His Italian experience turned out to be unfortunate in his first season, as Matías Silvestre and Giulio Migliaccio (a central midfielder adapted as a centre back) were preferred to him as starting centre backs.
On January 26, 2012 he was sent on loan to Lille until the end of the season, with an option for the team from Northern France to sign him permanently.
Cetto returned to Palermo after Lille opted not to acquire the player permanently, and was called up for the summer pre-season camp where he met new head coach Giuseppe Sannino, who then decided to keep him in the rosanero team for the 2012-2013 season. On Thursday, January 24, 2013, de Almagro from Argentina, a Primera A team, signed Mauro Cetto for 2 and a half years.
