Kylian Mbappe

“I am very happy to stay in France, in Paris, in my city,” Mbappe told supporters on the Parc des Princes pitch before he marked his new deal with a hat-trick in PSG’s 5-0 win over Metz in their final Ligue 1 match of the season.

tanding next to PSG president Nasser Al-Khelaifi, Mbappe said: “I hope I’m going to be able to continue to do what I like most — winning football matches and trophies with all of you.”

Mbappe’s hat-trick on Saturday took his total of league goals for the season to 28.

The French superstar‘s deal with Paris Saint-Germain expires at the end of the season, meaning Mbappe has been free to talk to other clubs about signing him on a free transfer.

The French World Cup winner has not extended his contract at PSG, fuelling speculation he will seek a move to Real Madrid at the end of the season.

The Spanish giants bid 180 million euros ($287 million) for Mbappe in August but PSG, who had just signed Lionel Messi from Barcelona, turned down the offer.

The French club’s sporting director Leonardo on Wednesday admitted that they will not be able to keep the World Cup winner “if he wants to leave”.

“Our position has always been the same, to keep Kylian and extend his contract,” Leonardo told several media including AFP as he discussed the future of Mbappe, whose current contract expires at the end of this season.

The 19-year-old forward appeared to hurt his left ankle in a tackle from defender Adil Rami during a practice match on Tuesday.

Mbappe, who is expected to be a starter in Russia, received treatment from support staff and attempted to play on before leaving the session, placing him in doubt for Saturday's clash with the Socceroos.

Didier Deschamps will hope the knock is only a minor concern after losing both Laurent Koscielny and Dimitri Payet to injury prior to selection of the final 23.

France's other Group C opponents are Denmark and Peru.

The 18-year-old made his Ligue 1 debut at 16 and has been a key figure in the Principality club's re-emergence at the top of French football this season, scoring six goals in 19 games.

Mbappe, a France U19 international, became the club's youngest goalscorer at 17 - a title previously held by Henry - and only signed a new deal with Monaco last year but Wenger, whose side play Chelsea at Stamford Bridge live on Sky Sports on Saturday, has admitted he is following the forward's development.
