Manchester United have confirmed that their first summer signing Memphis Depay has completed his medical with the club on 18 May.

"Memphis Depay has today completed his medical at Manchester United," a statement on United's official site read.

"The Club will now work towards finalising his registration when the international transfer window opens in June," the statement added.

The Red Devils confirmed the signing of the Dutch forward from PSV Eindhoven earlier in the month, but the move was subject to a medical, and with that complete the club can begin registering the player ahead of officially unveiling him as a United player when the transfer window opens on 1 June.

Depay has been the player of the season in the Eredivisie after scoring 20 goals in 32 games and taking PSV to the Dutch title for the first time in six years. Liverpool were also keen on signing him, but the player chose Manchester as he was keen on reuniting with former national team coach Louis van Gaal.

However, Red Devils legend Gary Neville has called for patience from the fans as he believes that Depay will take time to adjust to the Premier League and adapt to playing for a club of United's stature.

Despite that he is confident that the former PSV star is in line with United's transfer policy of recruiting young players with potential to become future greats, but warned him that there are many obstacles in his way before he can fulfil his true potential.

"It's a typical Manchester United signing to sign someone who has got potential but hasn't yet grown to become the finished product," Neville said, as quoted by the Daily Mail.

"United have done that over the years, particularly with foreign players. I think Depay looks like an exciting player but there's a lot of obstacles to overcome to determine as to whether he going to become the real deal," the former United defender explained.

"He's got to settle in the country and get used to playing football in Manchester. It will be different but it fits the bill in terms of him being a young player."
