Maybe
You're wrong, no?
I struggle to understand these panic reactions for CB position. Top 4 should be achievable with the squad we currently have + the addition of LB.
We've already signed Saliba for next season and defense looks solid on paper with Saliba, Holding, Chambers and Sokratis for next season.
If we really struggle defensively this season, there is an option to replace Özil and Xhaka with midfielders who are able to protect back 4 better. Chambers in front of defense with Torreira and Ceballos in front of him is one option, the other one would be more Willock, Ceballos and Torreira who are all capable of winning the ball and keeping possession. In both cases, there wouldn't be any passengers that we get with Xhaka and Özil.
