So Pogba has some certain really outstanding traits, but a lot of holes in his game. I reckon that since his youth days in France every team has played to his strengths, which made him better at what he does great but worse at what he does poorly. And you can't blame the teams because I assume even back then he was a potential star in the making, so why not cater to him?
Then he finally rocks up at United (the 2nd time) and now he's in a team that forces him to use the other aspects of his game he's waivered. He still has his moments, but he's forced to play a more rounded game and it doesn't suit him.
I reckon a lot of lesser but still very talented players have similar problems. Big fishes at youth level who have their teammates play for their strengths, but unprepared to be smaller fish at senior level.
I do wonder if that's part of the reasoning why City youth teams are all VERY team orientated these days?
