Funny you mention Man City as they play inverted wingers as well but they don’t seem to be having any issues starting their moves on the less ‘dominant foot’
YouTube videos from a league that is nowhere near the standard of the premier league is also not an indication he can cut it at this level. The top players shine or show glimpses wherever they play.

In any of the 9 (games) he's started over the entirety of this season.
