The Red Devils are looking for a new goalkeeper, with concerns about Andre Onana's suitability for the role. Manchester United wants a reliable goalkeeper to strengthen their team.

It is reported that Martinez's release clause is a significant factor in Manchester United's interest. This could make it easier for the club to sign him. However, the details of the release clause are not yet clear.

Martinez has been a key player for Aston Villa, and his departure would be a significant loss for the team. He has been with the club for five years and has become a fan favorite.
