Eleven years of his extensive professional career were spent at Atlético Madrid and Deportivo de La Coruña, where he won a total of five titles. Over 14 seasons, he appeared in 415 La Liga matches.
Molina's career was intimately related with Atlético Madrid, of which he claimed to be a fan. Signing in 1995, he helped the capital side win a double (league and Copa del Rey) in his first year, going on to miss only two league matches over four seasons.[4]
Joining 2000 league champions Deportivo La Coruña after Atlético's relegation, Molina helped win a Spanish cup and two supercups, being an undisputed starter throughout his stint in Galicia. However, on 14 October 2002, he announced that he suffered from testicular cancer,[5][6] and that he was forced to undergo treatment for his illness, thus missing most of the 2002–03 campaign (ten league appearances, as Depor finished third); he eventually recovered fully.[7][8]
After his link expired,[9] Molina returned home to Valencia for 2006–07, playing for top-division strugglers Levante UD, but did not renew his contract after the season's end, retiring subsequently after the club retained its league status.[10][11][12]
He was then included in the squads for UEFA Euro 1996 and the 1998 FIFA World Cup, but had to wait until Euro 2000 for first-choice status, although he was dropped after a blunder in the opening 1–0 loss to Norway and did not play afterwards.[15][16]
Molina reached Villarreal's main squad on 22 December 2011, taking the place of sacked Juan Carlos Garrido.[18] He was himself dismissed on 18 March of the following year after a 1–0 away loss against former club Levante, with the Yellow Submarine dangerously close to the relegation zone (17th).[19]
On 3 May 2016, Molina was announced as the head coach of Indian Super League side ATK, replacing countryman Antonio López Habas.[22] On 14 November of the following year, he was appointed at Ascenso MX club Atlético San Luis ahead of the Clausura tournament.[23] He was relieved of his duties by the latter on 18 February 2018 after just two wins in 11 matches in all competitions, with his side in last position in the league.[24]
