Coch was born in Tarragona, Catalonia. In June 2010, while still a youth player at Gimnàstic de Tarragona, he was called to train with the first team to cover for injured players. On 19 June he made his debut with the main squad, replacing fellow youth graduate Fran Vélez in the 82nd minute of a 0–1 away defeat against UD Las Palmas for the Segunda División championship.
On 10 July 2012, after spending three full seasons with the farm team, Coch was promoted to Nàstic's main roster, alongside Sergio López, Ñoño, Eugeni and his cousin Joel Coch. During the campaign he appeared in 13 matches (nine starts, 781 minutes of action), as the club missed out on promotion play-off qualification.
On 20 October 2013 Coch scored his first goal for Gimnàstic, netting the first through a free kick in a 2–1 home win over Valencia CF Mestalla; he was later linked to that opponent in January of the following year, but the deal collapsed.
