Introduction
David Querol Blanco (born 25 February 1989) is a Spanish professional footballer who plays for Albacete Balompié on loan from Cádiz CF as a forward.
Club career
Born in Reus, Tarragona, Catalonia, Querol finished his development at CF Reus Deportiu. He made his senior debut in the 2008–09 season, in Tercera División; in 2010–11 he scored a career-best 13 goals, helping his team return to Segunda División B.
On 27 April 2011, Querol agreed to a two-year contract with Real Betis, with the deal being made effective in June. He was assigned to the reserves who competed in the third level, but missed his debut campaign due to injury.
On 7 July 2013, Querol joined fellow league club Gimnàstic de Tarragona. He featured regularly during his spell – albeit mostly as a substitute – as the side finished fourth in the regular season and fell short in the promotion play-offs.
On 14 July 2014, Querol signed a two-year deal with UE Llagostera, newly promoted to Segunda División. He made his debut as a professional on 23 August, aged 25, starting in a 0–2 away loss against UD Las Palmas.
Querol scored his first professional goal on 18 January 2015, netting the last in a 2–0 home win over Real Valladolid. On 4 June of the following year, with his team already relegated, he netted four times in a 6–2 home rout of Real Zaragoza, taking his tally up to nine.
On 9 July 2016, Querol returned to Reus, now in the second level. In January 2019, he terminated his contract due to the club's poor financial situation overall.
On 30 January 2019, free agent Querol agreed to a two-and-a-half-year contract at Cádiz CF. Exactly one year later, he was loaned to fellow second division side Albacete Balompié for the remainder of the season.
