His position doesn't exist in our formation. We play with our leftback tucked in as a playmaker. His role at PSV was to provide width and whip in crosses, much like our fullbacks those few times we played 3ATB
It's weird how we've changed our fullbacks roles since Mendy's injury and with Delph and then Zinchenko as replacements. Because in the beginning Mendy offered width and wipped in crosses like a madman. To the point were Sané was redundant and began to get benched. I wonder why we don't change back, however Mendy seems worse at crossing than before
