Senne Lammens has played nine times for Belgium Under-21s
Manchester United have agreed a deal to sign Belgian goalkeeper Senne Lammens from Royal Antwerp for an initial 21m euros (£18.1m) plus add-ons.
It brings to an end United's interest in Aston Villa goalkeeper Emiliano Martinez.
Lammens, 23, is travelling to Manchester to sign a five-year contract at the Old Trafford club.
United are keen to address their goalkeeping issues with Turkey's Altay Bayindir making errors in the league and last season's number one Andre Onana at fault for a goal in their EFL Cup exit to League Two side Grimsby.
