Just for clarity, Matheus Nunes registered the 2nd highest speed of ANY player in the PL last season. The idea that Nunes is vulnerable to pace is simply gash, as is the idea that Khusanov has proven himself to be a level-headed defender.
Khus is a tremendous prospect. He is aggressive, pro-active, and physically blessed. He plays on the front-foot and takes no messing. He is loved for those reasons, and I am someone who thinks he is a fabulous prospect. IMO, he is a centre-back, and potentially a world-class one, but it is early days, and he doesn't need to be the stick to beat other players with.
