Paris Saint-Germain are exploring the possibility of signing Barcelona's Lionel Messi in the summer, sources have told ESPN.

Messi wanted to leave Barca in August after the 8-2 Champions League elimination to Bayern Munich, and sources told ESPN at the time that Manchester City led the chase to sign him.

However, sources have told ESPN that Neymar and PSG sporting director Leonardo also discussed bringing the Argentina international to France at that time and have not lost interest in him since.

"I cannot talk about it at the moment," PSG's president Nasser Al-Khelaifi said on Thursday when asked about Messi's future.

After PSG's 3-1 win against Manchester United on Wednesday, Neymar told ESPN that he wanted to play with Messi next season.

"What I want most of all is to play with Messi again, to be able to enjoy him once again on the pitch," Neymar said.

"He can play in my place, I have no problem with that! But I want to play with him next year, for sure. We have to do it next season."

Messi, Neymar and Luis Suarez have remained close since their days together at Barcelona, and the three have a WhatsApp group where they still talk.

Messi also is close with Angel Di Maria, Leandro Paredes and Rafinha, who are in Paris as well.

Messi's wage bill will be one of the stumbling blocks for PSG, as he earns €60 million a year at Barcelona, much more than Neymar's €36m a year or Kylian Mbappe's €20m a year at PSG.

Sources have told ESPN that the immediate priority for the club is securing extensions to Neymar's and Mbappe's contracts.
