Paris Saint-Germain star forward Neymar has talked to Lionel Messi over the phone on Thursday about the possibility of the Barcelona star reuniting with the Brazilian at PSG, according to a report by ESPN.

The same news outlet had also reported on Wednesday that PSG have been closely monitoring Messi's situation but are yet to make an offer or contact Messi's father Jorge, who is also the Argentine's agent.

Messi shocked the footballing world on Tuesday night when he informed Barcelona through burofax that he would like to see his future elsewhere, demanding to move away from Barcelona on a free transfer by triggering a certain clause in his contract.

Messi's decision comes after Barcelona completed a trophyless season -- for the first time since 2007-2008 -- that ended with a humiliating 8-2 defeat to German champions Bayern Munich in the Champions League quarterfinal in Lisbon on August 14.

And as per ESPN's report, Neymar has already started doing his bit to be reunited with his old Barcelona teammate. Neymar, who joined PSG from Barcelona on a record €222 million transfer, has remained close with Messi. The Argentine even insisted Barcelona to bring back Neymar to the club last summer.

The report also suggests that another PSG forward Angel Di Maria, who is Messi's national teammate, has also spoken to Messi.

With Financial Fair Play regulations, it would be difficult for PSG to make the deal happen but not impossible as sources have stressed on Thursday evening. With the departure of Edinson Cavani, Thiago Silva, Eric Maxim Choupo-Moting and Thomas Meunier, PSG have considerably reduced their wage bill.

Messi has also been strongly linked with Manchester City, a club where the Argentine could be reunited with Pep Guardiola, his former coach at Barcelona and the manager who oversaw his meteoric rise to becoming one of the greatest players in the world. ESPN had also earlier reported that Manchester City are considering offering Messi a long-term contract that would see him move to MLS partner club New York City FC after three years in the Premier League.
