Many accused Neymar of being greedy, many accused Mbappe of being greedy (quite rightly), but it looks like we have a champion: Messi.
What do you think of these numbers? This is absolutely Saudi Arabian level of payments and no adequate European club with non-corrupt management would ever sign such a contract.
Against the backdrop of these payments, Messi's tales of loyalty to the club look like a joke. He actually destroyed Barcelona, which fell into a financial crisis (by the way, they still pay him) and currently lost Olmo due to financial problems.
I believe you are one of the most active football analyst in this board, you should know better about comparism. If they say Mbape was been greedy, then he iis because he is just an average player that got the opportunity to win World cup with his ego been up there when he wasn't there in the first, similar to Neymar but he was even better than Mbape in my opinion but Messi, common, all of the other players that you mentioned performances reduced the moment the left their original club but Messi still remain at the top.
Look at how Neymar is struggling with his foot with injuries since he left Barcelona, Mbape is struggling everyday and working hard to be there, look at how he was playing in the last El clasico but when Messi was in Barcelona, he was been a god to Real Madrid players and even after he left, he is still who he is, he is the American guy every celebrity want to hang out and see him entertain them, he is worth every Euro he is been paid in his entire career.
