We have an excellent left back in Cancelo and our backups are comparable with our rivals as it stands.
The problem with Cancelo at left back is better teams work us out, they let Cancelo go down the line knowing the left foot is not his best and needs to cut back on his right, the key is balance on both sides and the forwards want a first time cross and make the run only for Cancelo to hold and cut back,
i also like the balance in giving us options of down both flanks to mix it up so teams down no have to defend us
