Goalkeeper Emiliano Martinez was not included in Aston Villa’s squad for their game against Aston Villa amid interest from Manchester United.
United are considering making a move for the 32-year-old Argentina keeper.
Palace defender Marc Guehi, meanwhile, who Liverpool have bid £35m for, was named in his side’s starting line-up.
United have been looking to address their goalkeeping issues and have been negotiating with Royal Antwerp about their highly rated 23-year-old Belgian Senne Lammens.
Lammens is keen to join United and has been left out of Antwerp’s past two games. It is known the Belgian Pro League club need to make a sizeable sale so they can meet an external loan they have previously taken out.
However, he lacks high-level experience, while Martinez is a World Cup winner with Argentina and a two-time Fifa goalkeeper of the year with 197 Premier League appearances under his belt.
After Saturday’s 3-2 victory over Burnley, United head coach Ruben Amorim admitted: “I think it is hard to be a Manchester United goalkeeper in this moment.”
