You're right, there are many that don't. But the ones that do could easily be sat at home in their downtime picking at caviar, so flying out to a third world country for humanitarian work is commendable and not cuntish behaviour; in my opinion. He has his petulant moments but fucking hell, which elite players haven't? I remember Erling having a hissy fit against Everton last season but he's still a down to earth lad. And I don't see how he's walked all over everyone to get his way. In truth, he is one of the greatest, in the bracket of top three players in the world; PSG offered him a bewildering, unprecedented contract that reflects that and he signed it, knowing he was still at an age where he could get his dream move down the line. He took advantage of PSG's recklessness, as any sane person would.
Football, as a sport, has many cunts in its orbit. I don't think Mbappe is one of them.
