It could explain why Konsa has improved so much this season. https://www.bbc.co.uk/sport/football/articles/c4gp6pmenl0o
I think Ezri has had great recent defensive performances. But, the one part that lets him down is his use of the ball at his feet. That is why having Pau alongside him in CD is vital. Ezri's passing of the ball is either sideways or back to Big Emi. I'm surprised that Unai or his coaches do not appear to have improved his ball distribution to a better level.
Lindelof will have to step in if there’s any issue. Not ideal but he’s there to cover for a few games if needs be and he’d be in his best position rather than at right back or defensive midfield.
