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 I ask you for how long has that rumor been circulating and how often has it been brought up again? That's part of the news like every couple of weeks and will be even more so the closer we get to the summer and the opening of the transfer market.
I wonder if Messi declines an offer from PSG because they don't want to pay him enough and he has to accept salary cuts, how is Barcelona going to stem the salary for Messi? That is the part I don't get here.
I think it is still everything possible and I hope he is not leaving for Saudi Arabia.
