Several football clubs are interested in signing Martinez, including Manchester United. The 32-year-old is reportedly waiting to see if Manchester United will make an offer for him.

There are doubts about Manchester United's current first-choice goalkeeper, Andre Onana. This has led to interest from other clubs, including Saudi Pro League teams.

Galatasaray, a Turkish football club, is also interested in signing Martinez. However, it seems unlikely that Aston Villa will sell him unless they receive a suitable offer for their current first-choice goalkeeper.
