Molinero was born in
Ontígola,
Province of Toledo,
Castilla–La Mancha. After spending two
La Liga seasons at
Atlético Madrid (his first game being on 25 September 2004, featuring the full 90 minutes of a 1–0 home win over
Villarreal CF), in whose youth system he grew, he served a
Segunda División loan stint at
Málaga CF. In July 2007, the
free agent Molinero joined
RCD Mallorca on a two-year deal. He appeared sparingly throughout
the season, moving
the following campaign to
Levante UD, recently relegated to the second division. Molinero signed with
Romania's
FC Dinamo București on 21 July 2009, leaving Spain for the first time in his career. On 27 August, he took the field for the second leg of the
play-off round in the
UEFA Europa League against
FC Slovan Liberec, winning 3–0 away and advancing on
penalties. He spent only
one year in
Liga I, however, cancelling his three-year contract in the summer and returning to his country with second-tier club
SD Huesca. In the 2011 off-season, Molinero joined
Real Murcia CF for three years. On 26 June 2014, having never appeared in less than 37 league matches, he moved to
Real Betis also in division two; he achieved promotion in
2015, contributing one goal to the feat. He returned to the second tier in July 2018, with the 33-year-old agreeing to a deal at
Sporting de Gijón. ==Career statistics==
