Paris Saint-Germain sporting director Leonardo says he can't promise star striker Kylian Mbappe will sign a contract extension with the Ligue 1 champions.

The 20-year-old is under contract until 2022 and Leonardo was asked if he should sign an extension in an interview with Le Parisien (h/t Get French Football News).

"That is not a question," he said. "I never make promises. For two reasons: the first is that I am not the person who does everything at this club; the second, I do not want to pluck promises out of thin air, without being certain I can keep to them. The only thing that interests me is stuff that is concrete, that is today."

Mbappe has emerged as PSG's most important player since joining the club from Monaco in 2017. He was the top goalscorer in Ligue 1 last season and was only outscored by Lionel Messi in the race for the European Golden Shoe
