The 22-year-old recently confirmed that he asked to leave PSG over the summer and is widely expected to sign for Los Blancos on a free transfer in 2022.
Perez recently claimed that he hoped "everything would be solved" over a transfer for Mbappe in January, but his comments have not gone down well with Leonardo.
Speaking in an interview with L'Equipe, the PSG chief said: "This is another example of the lack of respect for PSG and for Mbappe.
"In fact, in the same week a Real Madrid player [Karim Benzema], then the Real Madrid coach [Carlo Ancelotti] and now the president [Florentino Perez] talk about Kylian as if he was already one of their own. I repeat: this is a lack of respect that we cannot tolerate."
Mbappe has opened the 2021-22 season with four goals and five assists from 11 games in all competitions amid intensifying speculation surrounding his next career move. body check tags ::
