I'm with @Lxxx
on this one.
He doesn't seem tall enough, nor built sturdily enough to be a really successful Centre-Back in this league.
I know he can pack on some muscle, but his frame is small, and just over 6ft is on the short side.
I know Cannavaro and Puyol were both excellent, but neither plied their trade over here.
Just spitballing here, but maybe down the line he could do an Eric Dier and slot into a Defensive/Holding Midfield role.
