He'd have to be a central CB right? I've only seen bits but he seems a bit Zouma-like incredible physicality but a bit of a trampoline touch.
Also would he be able to replace Dier as the leader at the back? Dier being mature, experienced, multi-lingual as shown that we do need him to manage the back line Romero and Emerson in particular.
I think he can play left centreback too, he is decent at passing but it's physically it's where he is outstanding
