Kylian Mbappe is prepared to sign a new deal with PSG - but will insist on one special clause.

AS says Mbappé remains a priority target for Florentino Pérez and the PSG star has reportedly placed a demand on the Parc des Princes board in talks over a contract renewal.

The France international and PSG sporting director Leonardo are in an impasse and the striker is apparently unhappy with the way talks are progressing and while it is expected the 21-year-old will accept a new deal, he will demand a release clause that will permit him to move to Real Madrid or another of Europe's most storied clubs.

It will not be a cheap investment for potential suitors though, with any buy-out inserted into Mbappé's deal likely to eclipse the €222m PSG paid Barcelona for Neymar. Mbappé's contract expires in 2022 and Pérez's plan was to make his move when the striker had just one year left on his deal, which would lower the asking price considerably.
