Munir El Haddadi

After starting at Galapagar and DAV Santa Ana, Munir scored 32 goals in 29 matches playing for CF Rayo Majadahonda's Cadete A team, on loan from Atlético Madrid, after impressing during a trial in 2010. However, both Atlético and Real Madrid turned down the opportunity to bring him into their ranks. As a result, he attracted interest from a number of sides such as Manchester City, but signed for Barcelona's youth academy the following summer.

Munir made his UEFA Youth League debut with the Juvenil side against Ajax U19, where he scored two goals. He scored braces against Milan U19 and Copenhagen U19, finishing the tournament scoring 11 goals in 10 matches. He scored a brace in the final against Benfica U19. On 3 March 2014, he extended his Barça contract until June 2017.

After being an unused substitute against Tenerife and Deportivo de La Coruña, Munir made his professional debut for Barcelona B on 2 March 2014 in a 1–2 away win against Mallorca in the second division, coming as a 72nd-minute substitute for Sandro. He scored his first goal as a senior player in a 2–1 home win against Girona on 19 April.

On 24 August 2014, Munir made his official debut for the first team in La Liga, against Elche at Camp Nou. He started the match and scored the second goal of an eventual 3–0 win before being substituted after 67 minutes for Pedro. Eight days short of his 19th birthday, he became Barcelona's third-youngest goalscorer after Bojan and Lionel Messi. Munir was a nominee for the 2014 Golden Boy Award.

On 29 August 2014, Munir was called up for the first time as one of 21 players for Albert Celades' Spain under-21 team to face Hungary and Austria in September. However, after an injury to Diego Costa, Vicente del Bosque called Munir up to the senior squad for the first time ahead of a UEFA Euro 2016 qualifier against Macedonia on 8 September. He made his debut in that match, replacing Koke for the final 13 minutes of a 5–1 victory at the Estadi Ciutat de València. He said after the match he never considered playing for Morocco.

On 22 February 2015, Munir was sent off for two bookings in Barcelona B's 0–1 defeat at Llagostera, as the season ended with relegation to Segunda División B. He played three matches apiece in Barcelona's successful runs in the Copa del Rey and UEFA Champions League, but was not included in the matchday squads for either final.

Munir was an unused substitute for their 5–4 win over Sevilla in the 2015 UEFA Super Cup on 11 August. On 2 December, he scored his first Barcelona goals since his debut, scoring two in a 6–1 win over Villanovense as Barcelona advanced by the same score on aggregate in the domestic cup. On 17 December, starting due to Messi and Neymar's injuries in the semi-finals of the year's FIFA Club World Cup in Yokohama, Munir won a penalty kick when fouled by Guangzhou Evergrande Taobao's Huang Bowen, from which Luis Suárez finished his hat-trick to send Barcelona into the final, 3–0. The South American duo returned for the final, which Barcelona won 3–0 against River Plate with Munir unused.

On 13 January 2016, profiting from Suárez's suspension, Munir scored both goals in a cup win at city rivals Espanyol, putting Barcelona into the quarter-finals 6–1 on aggregate. He was unused for the final, a 2–0 extra-time win over Sevilla on 22 May, but with five goals was one of as many players to finish as the tournament's top scorer, among them Messi and Suárez.

On 14 August 2016, Munir came on as substitute on the 76th-minute and scored to double Barcelona's lead over Sevilla in the 2016 Supercopa de España first leg to give Barcelona a lead of two goals in the second leg.

On 30 August 2016, Munir moved to fellow La Liga club Valencia on a season-long loan. He was handed the number 9 previously worn by Paco Alcácer, who had moved in the opposite direction. Munir made his debut on 11 September, replacing Santi Mina after 63 minutes of a home game against Real Betis, and his rebounded header was scored by Ezequiel Garay in a 2–3 defeat. On 22 October, he scored his first goal for Los Che, coming on at half-time for Martín Montoya and equalising at the Mestalla against his parent club in a loss by the same score.

On 1 September 2017, Munir joined Deportivo Alavés on a season-long loan deal. He made his debut nine days later in a 1–0 loss at Celta de Vigo, replacing Enzo for the final 33 minutes. On 30 September he scored his first goal for the Basques, opening a 2–1 win at UD Levante. In the reverse fixture the following 1 March, he was sent off for diving in a 1–0 win at the Mendizorrotza Stadium.

In June 2017, it was reported Munir and the Royal Moroccan Football Federation (FRMF) had contacted FIFA to change his allegiance to the Atlas Lions. However, a FIFA spokesman denied any contact and said the player was ineligible for a switch. On Munir and the FRMF's request, the Court of Arbitration for Sport began debating FIFA's rules on switching allegiances in April 2018. His appeal to represent Morocco was denied on 14 May.

Munir was offered the chance to renew his contract with Barcelona before its expiration in the summer, but refused to do so. Barcelona assured him that he would not play for the club again and has been favored to be sold by Coach Ernesto Valverde, saying "it would be for the best". Several clubs from England and Italy were interested in the forward, but, in January 2019, Sevilla was able to claim him for a fee of around €1 million. The transfer was able to be completed before the transfer windows closed in January, rather than during the summer.

Munir scored a hat-trick on 7 November 2019 in a 5–2 Europa League group win at F91 Dudelange, which put his team through to the last 32 and bought his tally in the competition to five.

On 1 October 2020, following a rule change by FIFA that allowed a player to change their national team provided they made three or less appearances in qualifiers before the age of 21, Munir once again attempted to switch from Spain to Morocco and was called up to their national team. Nevertheless, this switch was also rejected by FIFA, on the grounds that Munir played for the Spanish under-21 team in September 2016, after turning 21.
