Lionel Messi would never have left Barcelona if Barcelona had not let go of Lionel Messi due to financial problems. Barcelona was a name of passion for Messi because the Argentinian star played for Barcelona from that small time to long time. Lionel Messi's performance was not that good at the time when Barcelona released Messi due to financial problems. After releasing Lionel Messi, Barcelona made several big transfers to their team. Barcelona signed stars like Raphinha Lewandowski after Messi left. After the end of Messi's contract with PSC this season, the Barcelona president wanted to return Messi to Barcelona again, but in the end, their efforts were not successful. Messi joined Inter Miami. Having failed to lure Messi back to Barcelona, Barcelona have signed former Champions League-winning captain İlkay Gündoğan.
After his exit from PSG things were clear he is not going to join Barcelona with most chances his next destination could be MLS or Saudi League because in presence of Xavi and due to financial issues it's never been option for both parties this was just rumours in news for the media intention which is not already ended because if Barcelona have him again then surely this was going to be big disaster for their preparations which are happening in presence of many youngsters which are doing impressive.
Barcelona current squad is surely capable of having better results then in presence of Messi and Xavi is also dealing impressively with this all right now with their current strength and performance they can defend their title easily.
