When you think about the lineup (and that Tuchel’s will probably stick with a back 5), it probably isn’t that bad.

Chilwell will only play left back but his fitness issues mean that Cucarella will also play there. Cucarella and Koulibaly can both play left centre back and at the moment, Silva in the middle although Koulibaly might play there too. Then right centre back is likely Fofana but Azpilicieta and James have also played there with Right wing back between James and Loftus-Cheek. Gvardiol is a decent signing and like you say, will replace Silva.

Given the crazy schedule of 2 games per week until the World Cup, they’re going to need all of these options and after mapping it out like that, it feels like they’ve got it right. Just a shame that the rest of the team is shit 🤣
