Leonardo joined PSG as their new sporting director last summer.
He told French radio station RMC: “I have great relationships with my former clubs but I am not in contact with Inter to go back and work there.
“It’s been 23 years since I left Brazil, and I have never left a country for personal reasons.
“I am very happy in Paris, but I don’t know if I’ll stay at PSG for 10 years or until June.”
