Messi then signed a two-year deal with Paris Saint-Germain, but with that contract expiring next summer, speculation has mounted over his future.
SunSport revealed yesterday that the 35-year-old has no concrete options currently on the table.
But he is not worried about that as his focus is on trying to win the World Cup in Qatar with Argentina.
However, Barcelona’s vice president has dropped a massive hint that they will make a move to re-sign La Pulga.
In an interview with El Matí de Catalunya Ràdio, Barca vice-president Eduard Romeu revealed that Messi’s return would be economically sustainable.
He said: “If I were to go back, it would come for free, so I’m sure it would be viable.”
PSG are understood to want to keep the star by offering him a one-year extension, but they have yet to officially make the offer.
