Jose Mourinho is keeping an eye on Jan Oblak and Kasper Schmeichel as possible replacement for Spain's David de Gea, Calciomercato.com reports.
The goalkeeper is a target for Real Madrid with the Spanish giants ready to offer £44million to sign him.
The Red Devils want £61million for the 26-year-old as they want to generate the needed income to sign top players during the summer transfer window.
De Gea was very close to joining Real Madrid last summer but he eventually decided to stay at Old Trafford.
He joined Manchester United during the 2011 summer transfer window, becoming one of the most important players for the club.
