Look at him go, with his ambipedal ways.

Josh has to be careful not to overrun the ball avoiding injury, when moving with it at pace with them long legged strides but the carries into the heart are very impactful in breaking compact blocks and defends well to boot. Multi-functional. Madrid & Bayern were after him prior to signing a long-term contract at Chelsea.
There's your reasons not to buy a CB.
Additionally, I'm fine with our current CB choices of Acheampong, Badiashile, Chalobah, Colwill, and Tosin (Sarr). Chalobah and especially Josh being the versatile ones that play well in multiple roles, need them around. Champions League standard.

Josh is a player above the level of Huijsen (who was given to the platform to breakout this season), without opportunities.
No idea why he's been limited. Actually, I do know.
