Paris Saint-Germain president Nasser Al-Khelaifi has said he is confident Lionel Messi will stay at the club and expressed his interest in signing Manchester United's Marcus Rashford on a free transfer.

Messi's contract expires in June and he's been linked with a move to Inter Miami of the MLS.

Messi could trigger a one-year extension with PSG as part of his his existing contract. 

"He's very happy, you can see that with the national team," Al-Khelaifi said.

"If a player's not happy you will see their performance not good for the national team. He performed fantastic this season for us, he's scored a lot of goals and assists for the national team and for the club.

"So what we agreed together -- that after the World Cup, [we] sit down together. But both sides -- our side of the club and him -- are very happy, so we will talk after the World Cup."
