Agree.
There are more suited players even in our team to play that position.
I'm just commenting on the article, and giving it a opposite (positive?) approach.
Well, to be fair, if used correctly, he doesn't have to be fast or strong, he just needs to be wide.
A wing-back has to cover for any eventuality on the outside of him and he's all alone in doing so - they have to be fast and practically indefatigable, and if not fast, absolute masters of positional play and defensive awareness.
Isolating and doubling up on wing-backs is par for the course and they have to establish themselves as dominant forces before they really get to open up and express themselves offensively. Sancho hasn't got great stamina, I'd barely call it average, but for the roles and way he is supposed to be utilised, what he does have is perfectly fine, especially so given he can suppress or occupy a flank in the attacking sense all by himself and take breathers between his basic combination plays and the times he does choose to up the pace and break into the sprints he wants to make - you don't get to choose when you're sprinting as a wing-back and it's a basic part of the job description.
There are some players who are wingers or attackers that you can see the logic in trying as wing-backs if you're feeling particularly wacky - someone like Daniel James, for example, but there are others it's just a stupid idea from the outset that will cause more harm than good - Sancho's only second to Mata in our entire attack as it being the dumbest position to put them in and expect anything but a catastrophe, I would say. Even a 36-year-old Ronaldo would make more sense.
Ole and co have no credit in the bank to try this, even a Pep, Bielsa or going back some years: a Zeman, would find a smarter fit (Rashford, I'd bet) if they wanted a wing-back from the selection of attackers we have.
Our staff have got a lot wrong this season, but this one is absolutely criminal, and I sincerely hope it's not true.
