According to sources, both Paris Saint-Germain and Munich have been mentioned as possible destinations, and contact has been made between the two parties.

Boehly, who is also acting as interim sporting director, is said to be attracted to the idea of signing such an icon at this point in his career.

According to sources, some at the club don't believe that head coach Thomas Tuchel is sold on the idea given that he has specific plans to change his forward line.

Romelu Lukaku was sent back to Inter Milan because he couldn't press effectively and there was a breakdown in relations.

The Portugal forward scored 24 goals in 38 appearances for United, but there were disagreements in the dressing room and he was let go in January.

Despite the player being given permission to miss training on Monday due to family reasons, United still insist they are not interested in letting him go.

They have been told that the player could be available from the other team, but so far, the coach has focused on other ways to strengthen the team.

They have made a £60m offer for Raphinha and are still in talks with Manchester City about the signing of Raheem sterling.

According to sources, Tuchel would like to see Robert Lewandowski move to England if he was willing to do so. The 34-year-old from Barcelona is one of the preferred destinations of the 29-year-old from Poland.

Sources have said that despite his affection for United, he would be willing to join a rival if it meant he could play in the European Championship.

Ronaldo was close to signing for City before he came back to United.
