I know he isn't, but the Prem Marketeers like to think he is.
Ronaldo and Messi have played in straight 4-4-2 systems before, the former with United for years.
It doesn't matter where the players roam. Every single time I watch Ronaldo play he takes it down the left flank. Who cares if he cuts it inside. The whole definition of a winger is someone who exploits space on the flanks . They're wingers, sorry.
