I also think it's harder to put the statistical numbers from centre halves into context too.Not a dig at anyone, and yeh, sexier positions naturally catch the eye; but I do think that people are somewhat prone to getting pre-occupied with the more exciting positions.
Laporte: I have my doubts about his durability/injury record.
Take Romero for instance he's generally thought of as a good defender but was part of a defence that conceded 60 odd goals
Levi Cowill could be a good option too. Doubt Chelsea would sell to us
Tapsoba, Bella-kotchap, max kilman ,ibanez have been mentioned.
Finding a left sided CB who is quick, a 1vs1 defender, good reader of the game, excellent with his feet who also needs to be good in the air. Probably harder to get than a 20 goal a season striker
