It's weird when peole start writing bad things about a player because we're not getting them. Mbappé's mentality has been pretty much universally praised by anyone he's ever played with or for. One of the reasons he made his breakthrough at 17 was because he was sensible beyond his years and his teammates in the French National team nicknamed him grandpa because behaves like an old man and not a teenager earning 300k/week.
There's literally no reason to accuse him of not having world class mentalities. Unlike Hazard, for example, who's gotten at least 2 managers sacked by giving up on them because he didn't like how they played him.
It is weird but it's not what I'm doing.
He made his breakthrough at 17 because he's mint, fast as fuck and fucking huge. He could have been a Lingard clone he'd still have broken through. It's my impression from the copious amount of reporting on him since he has been at PSG that he is becoming incredibly high maintenance.
