Domingos Quina (born 18 November 1999) is a Portuguese footballer who plays as a midfielder for Granada, on loan from Championship club Watford.
Despite being born in Guinea-Bissau, he has represented Portugal at international youth level. He is the son of former Portugal international defender Samuel Quina.
Having spent time at the academies of Benfica and Chelsea, he was offered a contract by Arsenal, but Quina decided to sign for West Ham United in May 2016 with the expectation that he would join the squad in July 2016 and sign a professional contract on his 17th birthday in November 2016. He made his debut, coming on as an 81st-minute substitute for Michail Antonio, against NK Domzale in the Europa League on 28 July 2016 and also played a part in the second leg in a 3–0 win in the club’s first ever match at London Stadium. On 3 October 2016, Quina scored a widely praised goal for West Ham Under 23’s, by scoring a chip from near the halfway line against Leicester Under 23’s side.
Having turned 17, Quina signed his first professional contract with West Ham in November 2016 which could keep him at the club until 2019. In the same year, he received two nominations for Premier League 2 “Player of the Month” for October, merited for his performances against Aston Villa, Middlesbrough and West Bromwich Albion respectively. His performances for West Ham Under 23’s saw Sky Sports describe Quina as a ‘wonderkid’.
On 9 August 2018, Quina signed for Watford on a four-year contract for an undisclosed fee, believed to be £1 million. He made his Watford debut on 29 August in a second round EFL Cup game away to Reading. With Watford already leading 1–0, Quina scored with a driving shot, described as “superb”, from 30 yards to make to score 2–0, the final result. He made his Premier League debut for the club on 4 December 2018 coming as a substitute in a 2–1 home loss against Manchester City and his first league start in the following match, on 10 December 2018, in a 2–2 away draw against Everton. On 15 December, he became the youngest Watford player to score in the Premier League, in a match against Cardiff City. On 1 February 2021, Quina joined La Liga side Granada on loan until the end of the season.
