I wouldn't be me if I don't bring some stats here 😅
Last season we conceded just one goal with Rudiger and Zouma pairing.
This season this trend continues.
Like Jason said, I don't trust him with 4 at the back even with Silva. They played that crazy game against WBA 3:3.
Yes he is better on the ball but clean sheets are essential. Plus Silva is already that ball playing CB, so why do we need two? Also he never scores unlike every other CB in the galaxy probably. He does look good in 3 at the back system so it's good now until Silva is back.
