Manchester United have agreed a deal to sign England midfielder Mason Mount for an initial £55million (€63 million) from Chelsea, the PA news agency understands.
The Red Devils will pay an additional £5 million dependent on appearances and success.
The 24-year-old is understood to have agreed a five-year contract, with an option for a further year.
Agreeing a deal for Mount helps to bolster the options for United boss Erik ten Hag in a key midfield area.
Mount came through the ranks at Chelsea, scoring 27 goals and providing 22 assists in 129 Premier League appearances.
The 24-year-old – a Champions League winner with the Blues in 2021 – has won 36 England caps and started the Euro 2020 final defeat to Italy.
