With Lionel Messi's time at Paris Saint-Germain drawing to a close, the Argentine forward will soon reveal his future -- but hopes of a romantic return to Barcelona are fading.

French champions PSG host Clermont in their final Ligue 1 match of the season on Saturday night, with Messi's future set to take centre-stage after that.

Coach Xavi Hernandez has been pushing hard for the World Cup winner to come back, but Messi's camp has told Spanish media no offer from Barcelona has arrived yet.

"For me there is no doubt that if Messi comes back he will help us on a footballing level, that's what I've let the president know," Xavi told Spanish daily Diario Sport.

Barcelona are waiting for La Liga to approve a financial viability plan ahead of spending in the summer transfer window.

"At the moment it seems difficult for Messi to return to Barca," said La Liga president Javier Tebas in April.

By contrast, elsewhere Messi will be paid a king's ransom, into the hundreds of millions.
