It's a 'myth' as you can think of one game to disprove it. Genius.
But hey, your opinion on Pogba has flip flopped that much this year zz pretty much anything you say on him can be taken with a large pinch of salt so I won't bother even trying to debate it.
When has my opinion flip flopped? I've been largely impressed with him this season considering everything and the weight of pressure he was under with that price tag.
I'm not going to reel off every game am I? I can say plenty off the top of my head, Arsenal at home, Spurs at home, City at home in the cup. He's been poor in big games like Chelsea, where everyone was and Liverpool, where the team was setup to contain and he was left as a no.10 for most part and had little to do.
