What's the problem with him as a winger, near the striker?

He's already played there plenty of times for United, City and Argentina. Also, it's a 4-3-3 winger, not a 4-2-3-1. Pogba and Asa will do most of the work in defence, it's not like if he has to cover all the $#@!ing flank.

Can't understand how it is a matter. He will/can drift inside a lot of times. He has the characteristics.
And wasting one of our midfield trio, making our wings play a bit further from the goal? No way.
