Manchester United have agreed a deal to sign England midfielder Mason Mount from Chelsea on a five-year contract for £55m, plus £5m in add-ons.
Mount, 24, will be Erik ten Hag's first signing of the summer.
Chelsea spent £600m last season and needed to sell before 30 June to ease Financial Fair Play concerns.
Chelsea had rejected United's first three bids but talks between the two clubs resumed this week to resolve the impasse.
It is understood Chelsea preferred not to lose Mount but were unable to successfully negotiate a new contract with his deal set to expire next year.
Mount, who has scored 33 goals in 195 appearances for Chelsea since making his senior debut in 2019, missed the end of the domestic season with injury as the Blues came 12th - their lowest finish for more than 25 years.
Mount won the Champions League in 2021 with Chelsea and started during the side's 1-0 win over Manchester City in the final.
He also won the Fifa Club World Cup and Uefa Super Cup with the Blues.
He has been capped 36 times by England, scoring five goals, and was part of Gareth Southgate's squad for the 2022 World Cup in Qatar.
Mount came through Chelsea's academy before joining Vitesse on loan for the 2017-18 season, scoring nine goals in 29 Eredivisie appearances.
