Good chance of being a really top player,my only concern is a lack of height for a centre back.
Cannavaro was smaller and he was one of the worlds best CB's for years. Now i'm not comparing the 2, just making the point that it may not stop Holgate becoming a top CB if he works on the rest of his game. Plus, although not the tallest, he has a very good leap so it may not become an issue.
