Aaron Wan-Bissaka has completed his Manchester United medical, Sky Sports News understands.
The 21-year-old defender completed the second part of his medical at Carrington on Thursday ahead of his move from Crystal Palace.
It is understood all the paperwork has now been completed and he has signed a five-year contract with the option of an extra year, with Wan-Bissaka set to earn more than £80,000 a week.
Wan-Bissaka's fee is expected to be £45m plus £5m in add-ons, which are understood to be based on appearances.
He flew to Manchester on Wednesday evening before completing the first part of his medical.
Wan-Bissaka, who was part of England's Euro U21 squad, will be Ole Gunnar Solskjaer's second signing of the summer after Daniel James joined the club from Swansea.
Sky Sports News first reported that Palace had rejected a £40m bid for Wan-Bissaka on June 8 but the two sides agreed a fee this week.
Should the deal go through as expected, Wan-Bissaka will become United's fifth most expensive signing of all-time behind Paul Pogba (£89m), Romelu Lukaku (£76m), Angel Di Maria (£59.7m) and Fred (£52m).
