The French champions want Messi to take a 25% pay cut from his existing salary which is worth €40 million gross a year, sources have told ESPN.

A new meeting between the club and Messi's father and agent, Jorge, is still scheduled for later this month to find a solution.

Sources have told ESPN that Messi was likely to sign a new deal before the World Cup but the situation has changed since then.

Messi has failed to replicate his excellent World Cup form with PSG and the club doubts whether Messi can still deliver in big Champions League matches.

The Argentina captain was disappointing as PSG were dumped out of the competition by Bayern Munich last month.

Sources have told ESPN that Messi is not prepared to reduce his wages and was upset after his name was jeered by a section of the club's supporters in the previous two home matches.

ESPN sources added that the 35-year-old is leaving all doors open for other teams to make him an offer.

His father had already discussed the possibility of a Barcelona return but financially it will be difficult to achieve while the player's camp is also awaiting a proposition from Inter Miami and Major League Soccer.

According to sources, Messi is open to playing in the U.S. before his career comes to an end while there remains interest from Saudi Arabia club Al Ittihad.
