It is rumoured that Messi's father has met Barcelona already but there isn't any agreement for Messi to return for now. However I'm quite confident that Messi is looking forward to returning home.
He has been doing a really good job at PSG so far. He has impressed people with his performance for his new team as well. However it still looks like he doesn't feel himself belonging here. He doesn't look willing to extend his contract either. In this case I would also like to see him back at Barcelona. Maybe Xavi is building a different team now but Messi would be welcomed happily there anyway.
But with things like this and wanting to force Messi back to Barcelona, they have to be prepared to sell some of their best players.
Messi's return if it really happens will further make their balance not improve especially now they also have to prepare around more than 170 million to balance their coffers and when Messi returns it means they have to empty more funds and of course selling star players is the way.
But on the other hand, I think it won't be worth it even if Messi's presence will bring a little blessing from sponsorship.
Barcelona have publicly admitted their desire to bring Messi back to the Nou Camp, with vice president saying that the club are eager for him to return. And to me, that’s the reason why Messi is reluctant about signing a new deal with Paris Saint Germain because he has been linked with a sensational return to the Catalan side this summer. However, Barcelona's continued financial difficulties could prove to be a hindrance in terms of getting a deal done and that’s where they’ll have issues.
