With Monaco's interest in Andre Onana on the rise, a potential replacement for Onana is emerging, and Martinez is at the top of the list.
The key to making this transfer happen could be Lisandro Martinez, Manchester United's Argentina defender.
According to sources, Emi Martinez and Lisandro Martinez are close friends, which could be an important factor in Emi's decision to join Manchester United. Martinez has already turned down offers from other top clubs in the hopes of joining Manchester United.
Manchester United's manager, Ruben Amorim, is a big fan of Emi Martinez and tried to sign him for Sporting in 2020 but ultimately lost out to Aston Villa. Amorim believes that Martinez has the qualities of a leader and a captain, which are essential for his squad.
