Swansea City winger Daniel James is set to become Manchester United’s first signing of the summer after his club accepted a fee that could rise to around £18m for the Wales international.

According to the Guardian, the 21-year-old is undergoing a medical at United on Thursday, after Wales gave him permission to leave their training camp, with the winger poised to sign a long-term contract.

United’s interest in James first surfaced towards the end of the season but the move was put on hold after the player’s father, Kevan, died suddenly. With James back in the international fold this week, after telling Ryan Giggs, the Wales manager, that he felt up to joining up with the squad, the wheels were set in motion for his transfer to go through.

It is understood that United will pay £15m up front for James, who had 12 months remaining on his contract at Swansea, with the rest to follow in add-ons. He will be Ole Gunnar Solskjær’s first signing, with the United manager looking to rebuild after a hugely disappointing end to the campaign.
