Asked for a comment on his fellow defenders, he said: "They've all got different attributes but the ones I've seen so far are good. I know I've been brought in to help tighten up at the back and I'll put everything I have into it. We have a new-look defence and it will take a while to get used to playing together but if you want to be a great team you need a well-drilled defence and communication is key to that."
