Former FC Barcelona captain Lionel Messi on Sunday confirmed he could join Paris Saint-Germain (PSG) after his reluctant departure from the Spanish giants.

The 34-year-old Argentina superstar is a free agent after his contract at Camp Nou expired.

Asked about possibly joining the Parisians, Messi told a news conference: “That’s honestly one possibility, to reach those heights. At the minute, I’ve got nothing confirmed with anybody.”

According to Messi, there has been interest from a host of clubs in signing him.

He did not mention any other potential suitors, and only the richest clubs in the game are likely to be able to afford to acquire him, given his high wages.

“When the press release was published (that I was leaving FC Barcelona), I had a lot of calls, a lot of clubs that were interested,” Messi said.

“At the minute, I’ve not got anything closed but we’re talking about a lot of things.”

Asked about the possibility of facing FC Barcelona with his next club, he added: “The people in Barca know me, they know I’m a good player and they know I like competing.

“If I’m going to come here, then like I did here I’ll fight to win everything. The last years of my career I’ll finish it in my way, competing and fighting for titles, ending my career on a high.”

Last year Messi had asked to leave the club via the Spanish post’s burofax service but changed his mind.

This time he came to an agreement to stay but financial stumbling blocks at Barca meant La Liga would not allow the deal.

He is out of contract and will leave for free, with Messi saying a PSG move is now “possible” but that he has no final agreement with anyone at present.

“My family and I were convinced I wanted to stay here, that’s what we all wanted more than anything. We thought we’d be staying here in Barcelona, today I have to say goodbye to all of this,” he said.

“We’ve always made this our home, we’re at home and we thought we’d be staying here in Barcelona.

“I’ve been here so many years, my entire life since I was 13. After 21 years I’m leaving with my wife, my three little Catalan-Argentine kids, and I can’t tell you we won’t come back because this is my home, and I promised my children that.”

Messi wanted to leave Barca in 2020 amid a disagreement with then club president Josep Maria Bartomeu.

However, he insisted he was wholly committed to staying this time around.

“Last year I wanted to leave, but this year I didn’t. I was always completely up front about everything and I have to leave the club I love,” he added.

“This is the most difficult moment of my career. I have been through tough moments, defeats… but the next day you go back to training and you have another chance to avenge yourself.

That isn’t going to happen here, it’s the end. Now another chapter starts.”

The coronavirus pandemic also meant Messi played almost the last season-and-a-half of his Barca career without fans in attendance.

Asked if he would return to bid farewell to a full Camp Nou, he replied: “Obviously, for these people, I’m available for anything. Honestly, yes.

“I never imagined it this way. I leave this club without seeing the fans for a year and a half. If I’d imagined it, I would have imagined it with the Camp Nou full and being able to say goodbye properly,” the Argentina captain said.

Messi won 35 trophies with Barca, but acknowledged he feels the Blaugrana were lacking just one more title.

“I would have liked to have won another UEFA Champions League,” he said.

“We got to the semi-final (in 2019) and were knocked out by Liverpool. That’s football. But I don’t regret anything.

I tried to give my best, and sometimes it works out for the better or worse. I’m of the opinion we could have won more, but I achieved my objectives.”
