Are we really talking about size when it comes to wingers?
We signed Memphis who was a physical freak/specimen at winger and he struggled.
We've also seen the likes of Hazard, Sterling, Grealish and Bernardo Silva all take to the league quite well at either the same size, or smaller, than Antony.
Even Raphinha who he gets compared to often is the same weight and weighs a bit less but has still looked comfortable in the Prem.
If he can't adapt to the league it won't be because of his physical attributes. If he does it won't be because of it either, it will be because of his technical ability, effort and role in a familiar system.
