I wish Barcelona wanted to bring him back into the team instead of retiring him. Frankly, it would be fun to watch him in the Barcelona jersey again, but he chose USA and he plays very well in MLS. Barcelona does not have the financial power to sign Messi again. He could have made the same sacrifice as Joao Felix and played for Barcelona, but Messi did not choose to do so. That's why we can't criticize him, it's his decision.
Barcelona and Messi already have their own world and we must realize that wanting Messi back in Barcelona uniform is impossible because in the end there are more negative impacts that will be received than the positive aspects obtained.
Indeed, seeing Messi in Barcelona uniform may be for some fans it will be a little better in the hope of repeating the glory in the era that has been lost but a Messi whose age is currently approaching retirement will not be able to carry that burden because he must be aware that with his current age he has decreased in terms of performance.
On the other hand, the salary that will be issued will also be very risky to make Barcelona experience problems again after this season its financial condition has improved so rather than taking risks like that, I think Messi's decision to MLS with the money given and Barcelona not bringing Messi is already a good decision.
