Mason Tony Mount (born 10 January 1999) is an English professional footballer who plays as a midfielder for Premier League club Manchester United.

[8] Citing Frank Lampard, Luka Modrić and Andrés Iniesta as his favourite players,[9] Mount eventually joined Chelsea in 2005.

[26] On 15 May, Mount scored his eleventh goal of the season in Derby's 4–2 win at Leeds United in the Championship play-off semi-final.

While the entire squad was forced to self-isolate due to Callum Hudson-Odoi's positive COVID-19 test, Mount had gone to play football with friends, including West Ham United's Declan Rice.

[39] Mount started the 2020–21 season well, as he featured in all Chelsea matches including the one against Barnsley in the third round of the EFL Cup on 23 September, which ended in a 6–0 win at home.

[41] In the next fixture, Mount missed the decisive penalty in Chelsea's 5–4 shoot-out loss away to Tottenham Hotspur in the fourth round of the EFL Cup on 29 September.

[43][44] On 24 January, he captained Chelsea for the first time in a 3–1 win at home over Luton Town in the FA Cup fourth round.

[49][50] In the second leg at Stamford Bridge on 5 May, he scored the second goal in a 2–0 win, which helped Chelsea advance to the Champions League final 3–1 on aggregate.

[51] Early in the season, Mount's presence in the Chelsea and England starting line-ups was alleged by fans and media to be because of favouritism by respective team managers, Lampard and Gareth Southgate.

[60][61] On 16 December, at 22 years and 340 days, Mount became the youngest Chelsea player to score 20 Premier League goals in the competition's history.

[71] Mount had a difficult start to the new 2022–23 season, as he registered no goal contributions in the Blues' first seven games under Thomas Tuchel, despite featuring in each match.

[74] Mount picked up two assists, for teammates Kai Havertz and Christian Pulisic, in a 3–0 home victory against Wolverhampton Wanderers on 8 October.

[75] Later in October, in a 2–0 away win in the Champions League against AC Milan, Mount won a penalty, after being fouled by former Chelsea teammate Fikayo Tomori, which Jorginho scored.

[77] On 27 December, in Chelsea's first match since the conclusion of the World Cup, Mount scored his first home goal in over a year against Bournemouth, in a 2–0 victory.

[78] On 27 April, Chelsea confirmed that Mount had undergone surgery for a pubic bone injury that had restricted his appearances during the second half of the 2022–23 season.

[80][81] On 5 July 2023, Mount signed for Premier League club Manchester United on an initial five-year contract, with the option to extend for a further year.

[84] Mount made his competitive debut for Manchester United in the team's opening game of the 2023–24 Premier League season – a 1–0 win over Wolverhampton Wanderers at Old Trafford on 15 August – playing 67 minutes before being substituted for Christian Eriksen.

[87] On 26 September, he returned from injury for a 3–0 win over Crystal Palace in the third round of the EFL Cup, playing 45 minutes and recording his first assist for the club.

[89] On 17 March 2024, Mount returned to the Manchester United first team, playing 15 minutes as a substitute in a 4–3 FA Cup quarter-final win over Liverpool.

[96] Following his impressive season with Vitesse, Mount was invited by manager Gareth Southgate to train with the senior team for a week ahead of the 2018 FIFA World Cup.

[108] He made his World Cup debut on 21 November, playing 71 minutes of England's 6–2 win in their first Group B fixture against Iran before being replaced by substitute Phil Foden.

[109] Five days later, he played the full 90 minutes in England's 0–0 draw with the United States but was criticised for his lack of impact on the match by several media outlets.
