Paris Saint-Germain sporting director Leonardo hit out at Real Madrid for their "lack of respect" for the Ligue 1 giants and Kylian Mbappe amid their public pursuit of the French star.
After soon-to-be free agent Mbappe confirmed this week that he had asked to leave PSG before the start of the season, Madrid president Florentino Perez seemed to suggest the France international could join the LaLiga powerhouse in January.
While Perez claimed he was misinterpreted, Madrid star Karim Benzema said a move to the Santiago Bernabeu is a "question of time" as Los Blancos head coach Carlo Ancelotti told reporters he hoped Mbappe "enjoys himself" in the Spanish capital.
Leonardo has not taken kindly to Madrid's open desire to sign the 22-year-old.
"This is another example of the lack of respect for PSG and for Mbappe," Leonardo said in an interview with L'Equipe.
"In fact, in the same week a Real Madrid player [Karim Benzema], then the Real Madrid coach [Carlo Ancelotti].
"Now the president [Florentino Perez] talks 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 scored four goals and supplied three assists in nine Ligue 1 appearances this season, while he is yet to add to his tally in the Champions League through two matchdays.
