Jesse Lingard is leaving Manchester United to join West Ham on loan for the rest of the season.
West Ham will pay United a loan fee of £1.5milllion and cover Lingard's £100,000-a-week wages for the remainder of the campaign.
Lingard, 28, who has been at United since the age of seven, has become marginalised this season and was desperate to play regular football by relaunching his career elsewhere.
Newcastle and West Brom were also interested in taking the former England midfielder on loan, but Lingard's preferred option was West Ham and a reunion with ex-United boss David Moyes.
Moyes is convinced he can help Lingard rediscover the form that made the midfielder an automatic pick for England on their march to the World Cup semi-finals in Russia in 2018.
Since then, Lingard has struggled to maintain a regular starting place for United, making just three appearances this season, two in the EFL Cup and one in the FA Cup.
United triggered a one-year extension option on Lingard's contract, which now runs until 2022, to protect his market value, but boss Ole Gunnar Solskjaer was happy for him to leave on loan.
Lingard, who has made 210 appearances for United, scoring 33 goals, won the FA Cup, League Cup and Europa League during his time at Old Trafford, as well as earning 24 England caps.
West Ham were able to move for Lingard as their second domestic loan slot became free, after they agreed to sign Said Benrahma on a permanent deal for £25million.
