For me Mellor just wasn't up to the pace, constantly made mistakes such as mis-judging the bounce of the ball etc AND for a 'ball playing centre half' the amount of misplaced passes from him into midfield was laughable not to mention the long field punts that went out for a throwing.
Brown, again wasnt good enough, he wasnt as bad as Mellor but he was still poor, he doesn't offer anything going forward and also makes many mistakes defensively, he doesn't seem to have that footballing brain.
Tarkowski on the other hand was excellent, vocal and kept the score at 1-0, and for me he was a good shout for MOM, I would of given it to Korey Smith in the end though.
