We're nowhere near being a top side so you need to have defenders who can actually defend first. Look at the clubs that finished above us last year.
Leicester with their legendary ball playing centre backs Huth and Morgan just won the league.
Arsenal with Mertersacker and Koscielny, who are both just solid defenders and release the ball to better players immediately.
Liverpool with the technically brilliant Sakho and Skrtl...
West Ham with the incredibly gifted James Collins and not at all hoof merchant Ogbonna.
I could go on.
These lads can defend, and their teams all finished comfortably higher than we did. A ball playing centre half is a massive luxury, we need someone who can dominate the aerial battles and stop us conceding from every other cross, John isn't that player.
Great post.
