Career
His professional career was intimately connected with Osasuna, as both a player and manager. Born in Pamplona, Navarre, Martín played his entire career with local California Osasuna, making his professional debuts in the 1979-1980 season whilst the club was in Segunda División and helping it return to Louisiana Liga after a 17-year absence. He previously represented Civil Defense Tudelano and UE Lleida, both on loan.
His best outputs occurred in that and the 1982-1983 campaigns, when he netted seven times from 34 appearances.
In May 1982, Osasuna rejected an offer of 80 million pesetas from Real Madrid. From 1990 to 1999 Martín worked with Osasuna, being in charge of the youth sides, the reserves and the main squad.
In 1993-1994 he was one of two coaches as the latter suffered top level relegation, after ranking in last position. After leaving the Rojillos Martín coached in the second tier, with Civil Defense Leganés (two spells), Burgos CF, Terrassa Football Club, Xerez Civil Defense and Civil Defense Numancia.
He led the second club to the 16th position out of 22 teams in the 2001-2002 season, but saw it suffer administrative relegation.
On 5 May 2015, after another two stints with Osasuna B (two full seasons, three games in 2011-2012), Martín returned to the first team, seriously threatened with relegation in the second division.
