FC Barcelona president Joan Laporta says the club is Lionel Messi's "home" as they look to re-sign the forward this summer.

The Argentine's contract at Paris St Germain expires in June, with reports linking him to Saudi Arabia.

But in an interview with Spanish broadcaster TV3, Laporta said Barcelona can compete with anyone for the 35-year-old's signature.

"History backs us, the feelings are too strong, we have 400 million fans around the world too," he said.

Messi left the Catalan giants two years ago after 21 years at the club but has struggled during his two seasons in France, with fans booing him after their 5-0 win over Ajaccio at the weekend.

Laporta said there had been an "affectionate conversation" between the two and that he congratulated Messi on winning the World Cup in Qatar last year.

"He is a PSG player and we have to wait until the end of the season, until it is over, and then we can talk more calmly about this," Laporta added.

"With all due respect to Saudi Arabia, Barca is Barca, and it is home."

The comments come after Barcelona won their first La Liga title in four years with a 4-2 win over Espanyol on Sunday.

Laporta appeared to be more reserved than during a late-night Twitch stream after the win, on which he is reported to have said the club would do "everything possible" to sign Messi.

Barca's economic situation limits them from matching what Messi could potentially earn in the Middle East, but they are hopeful La Liga, who have strict financial fair play regulations, will allow them to make signings this summer.

"The club is following an austerity plan, but we are working hard to build a competitive team for next season," Laporta added. "We will see if La Liga approve our viability plan."

Laporta also added that it was "unpleasant" to see Messi being jeered by PSG fans.

Messi's treatment in Paris contrasts with the affection still held for him in Barcelona. Fans gathered at Canaletes at the top of La Rambla on Sunday, where supporters go in the city to celebrate titles, chanted his name as part of their celebrations.
