It seems we have the natural heir to the aging Rooney. If he's playing centre forward of course he's performing poorly because he's a natural number 10. If he's playing number 10 of course he's playing poorly because these days he's a better central midfielder. If he's in midfield of course he's playing poorly because he's a striker.
I'd love the same protection in my job. I'd be sending emails to the wrong person, disrespecting customers and mismanaging staff; whilst the CEO says "of course he can't write an email coherently, his natural talent is speaking to customers", then when I lost an important customer because I was disrespectful "of course he's useless when dealing with customers, he's naturally a production guy".
Play him in a midfield two "he lacks protection", play him in a midfield three on the left "he's not advanced enough", play him as a number 10 "he's not able to pick the ball up from deep to ping a pass or drive through midfield".
Truthfully he's been here for over three years and the only thing consistent about Pogba is his absolute inconsistency. He will be poor 65-75% of the time irrespective of his position because that's just him as a player. The things he regularly tries to attempt on a football pitch inherently have a low success rate so it's obvious that a great performance would be far more of a rarity than a poor one.
