Brazil midfielder Fred is expected to be confirmed as a Manchester United player later this week, Sky Sports News understands.
The club have been waiting on a work permit for the Shakhtar Donetsk star but that is expected to go through imminently.
Earlier this month United announced they had reached an agreement with Shakhtar and that "a further announcement will be made in due course".
Fred will become United's second signing of the summer for a fee reported to be in excess of £50m.
He is currently in the Brazil squad at the World Cup, but was an unused substitute for the 1-1 draw with Switzerland in their opening game.
Earlier this month, United completed the signing of defender Diogo Dalot from Porto. The 19-year-old is understood to have signed on a five-year deal for a fee of around £19m.
