Joan Isaac Cuenca López (born 27 April 1991 in Reus, Tarragona, Catalonia) is a Spanish footballer who plays for FC Barcelona B as a right winger.
Cuenca joined FC Barcelona's La Masia in 2002, aged just 11. Halfway through his third youth year, however, he returned home and joined local CF Reus Deportiu, remaining with the club a further three (full) seasons.
Cuenca finished his formation with CF Damm and Barcelona, rejoining the latter in 2009. He made his senior debuts in the 2010–11 season, being loaned to yet another Catalonia club, CE Sabadell FC in the third division. He made an immediate impact, starting in 24 of his appearances and totalling 2,288 minutes as the Arlequinats returned to the second level after a 18-year absence.
In June 2011, Cuenca returned to Barcelona and joined its B team, alongside Martí Riverola. Shortly after, we was called by first-team manager Josep Guardiola to the pre-season, and made his debut on 23 July against HNK Hajduk Split.
Cuenca made his official debut for Barça B on 4 September 2011, playing the last 29 minutes in a 4–0 away win against FC Cartagena, and scoring the last goal of the match. On 19 October, he made his first official appearance for the main squad, replacing David Villa in the dying minutes of a 2–0 home success against FC Viktoria Plzeň, for the season's UEFA Champions League.
