PSG chief Leonardo admits he cannot guarantee securing Kylian Mbappe to a new contract.
A long-term target for Real Madrid president Florentino Perez, Mbappe committed to PSG for the new season, though talk of a new contract is another matter.
A situation Leonardo confirmed to Le Parisien, stating: "If it is necessary to renew? I never make promises for two reasons: the first is because I am not the one who does everything in the club and second because I don't make far-fetched promises without having the certainty of being able to maintain them.
"The only thing that interests me is the concrete, the actuality."
