Mauricio Roberto POCHETTINO Trossero is an Argentine former professional footballer who played as a central defender. An Argentine international for four years between 1999 and 2002, Pochettino represented the country at the 2002 World Cup and the 1999 Copa América. He spent 17 years as a professional player, 10 of which were in La Liga with Espanyol. He also played in France for two clubs, Paris Saint-Germain and Bordeaux, having started his career with Newell's Old Boys. Pochettino started his professional career with Newell's Old Boys in the begining of the 90's. Newell's was a crack team managed by "crazy" Marcelo BIELSA. POCHETTINO won two argentine leagues in 1991 & 1992. He was a great hope for argentine football and his association in centre back with Fernando GAMBOA was marvelous. Both have a good reading of the game despite their yougness. Then he moving to RCD Espanyol in Spain in 1994–95 as the Catalans had just returned to La Liga.
He was an undisputed starter in his six and-a-half seasons stay, helping the club to the 2000 Copa del Rey. It was at this time than he became an argentine international starter. In January 2001, Pochettino moved to Paris Saint-Germain. He was also a regular starter during his stay, but the club knew many difficulties at this time and by the way his results are mixed. After two seasons he moved for 2003–04 to fellow Ligue 1 outfit FC Girondins de Bordeaux but it was not a great memory for him and the team. However, he returned to Espanyol midway through his first year for two and a half more seasons, still being regularly used except for his last one, and wrapping up his career at the age of 34 with another domestic cup. In his two combined spells at Espanyol, he appeared in nearly 300 official games for the club.
