Well i don't blame the fans impatience because alot was spent to bring Messi into the team to help them secure the Champions league trophy but they couldn't even reach the semi's and that broke the heart of both fans and club owners because that was a trophy they desperately needed so they invested lots of funds to make it happen but to no avail, imagine having a team made up of Messi, Neymar, Mbappe and several other and they fail to meet up to their demands, i believe that's why they got fed up and the player on noticing that decided to leave.
But i feel if they had tried to keep him for another season like they did with Mbappe, he would had performed better than last season of which he's recently doing in his current club at Intermiami baging goals in every match.
Yes but the same guy they are blaming for not winning the Champions League did win the World Cup with Argentina. He can't be that bad can he? It wasn't him alone, it was a deficiency in the balance that PSG had. You brought up Mbappe, Messi and Neymar. Now imagine if they also had Ronaldo, Haaland and Lewandowski. It was too much and they couldn't cope with their attackers to not start defending in the last third of the pitch. That's why mistakes happened in the defense and why they were overwhelmed at times because you can have one Messi, or maybe a Messi and Mbappe, but having three attackers who just stay in front and wait is not balanced enough.
Even most of the time blame games started when we fall behind the expectations and same happened in this case with Messi is GOAT and have enough achievements which are not possible for the all and no doubt he won World Cup with Argentina, but this was not completely alone his achievement with soccer is team game, and we need to be best from other players as well but in PSG case we have no player's chemistry for the win of Champions League mostly are giving individual efforts which are never been enough for the win of trophy.
Now PSG management have enough time and sources to allow Luis Enrique for settling a good winning unit and won trophies for them with this is not possible in one or two seasons they have to allow him for nearly four or five years which is surely going to be better for them and coach as well-to-do enough changes and bring suitable players for the best.
