Agreed. He looks just as good on either flank when he is on his game. He just wasn't very much late in the season coz he for burned out. We need to keep him fresh and rotated.This is a myth. He works perfectly well at right back. The issue is, is that he isn’t Walker.
For about 10-15 games in a season, we need defensive full backs. This is where Walker should play.
The rest, Cancelo can play.
He looks better at left back as he’s replacing either Mendy or Zinchenko, who aren’t in Walker’s league.
