You may also wonder how serious Messi's grief is that he has to leave the club. Last year he had already made the decision to leave the club, and at the last minute it fell through. If you really love your club so much, why would he want to leave last year? I think it's a stage. with Crocodil tears.
Next day he was cheering in paris

Come on, it would probably have been the same grief if he left last year. He had been in the club for over 20 years. Why would you call that Crocodile tears?
The reasons he wanted to leave last year may have been personal. I am sure you know what the atmosphere was like, but that does not take away the love he had for the club in the past 2 decades.
