Real Madrid will reportedly block any attempt from Manchester United to sign central defender Raphael Varane next season.
United continue to be linked with defenders as the club look to find a permanent partner for Harry Maguire going into the 2021/2022 season.
Varane, meanwhile, is in the final year of his contract with LaLiga champions which would allow him to sign a pre-contract with any club in January.
However, it seems United may need to look elsewhere to bolster their defence as Los Blancos manager Zinedine Zidane does not want his countryman to leave.
"It's not just me [who wants to keep him]," Zidane said, as per Manchester Evening News.
"He is part of this club, we were very lucky to be able to bring him to Madrid.
"He has a great career, he's achieved a lot since he's been here. Of course, he is untransferable for the club, for the coach that I am, for people in general.
"That's clear and unambiguous. Now we can't stop people from talking. They're not just talking about Varane, but about all the players, Real Madrid ones and others.
"But for Varane, my position is clear, and it's the same as the club's position."
