The ill treatment that Lionel Messi got from Barcelona's president and some members of the the club's is still unbelievable and embarrassing many football fans and to the greatest footballer to have ever graced the beautiful of game of football. Messi left the spanish giants when he least expected to leave and that's why I think it'll be very difficult to convince him and bring Messi back to the Camp Nou again.
But that being said, there's possibility to lie him back to Barcelona and that's because of his love for Barcelona and fans of the football club. The PSG fans in recent times has criticised Messi because of the club's performances this season.
Yes, I agree; it's all about media hype, and we have very low chances for the Messi is going back to Camp Nou for his last few years in soccer most chances he will stay here in PSG with most chances we have no other club in UEFA which is going to have him in case of he will leave PSG then most chances his destination will be MLS or any Arab League because we already have few luxury deals for him from Saudi Arab Professional league which are important but currently no under his radar as he is looking for better options into UEFA.
Things are not ideal here in PSG, but we can expect any big change with most chances PSG management will try to offload Neymar and few other players for having changes in their midfield and defence which will bring positive changes and new coach is also vital for them, but all will be clear in June or July as right now they are just looking for the Ligue 1 title.
