I think we just have three very good centre-backs. All three must be in the league's top 10. Hartley was good last night in my opinion, too. Not getting the criticism.
Not a great game or performance, but it improved in the second half. Good to keep the clean sheet. Our man of the match was probably Cox, although Boateng, Hartley and Nelson were also good. McCormick and Mellor were dodgy.
Cox is a very unsung player for us - we look much better defensively when he is in the team. Only thing is, when Cox is in we miss Simpson's unsung attacking ability to keep the play fluid and ticking over. Boateng is too good to be dropped, so it looks like a straight choice between Simpson and Cox (and possibly McHugh) to partner him. If we choose Cox, our attacking play suffers, but if we choose Simpson our defensive play suffers. It's not that Simpson is a liability defensively or Cox is a liability going forward. It's that both are naturally very good at their favourite thing, and we miss Cox's defending and Simpson's attacking when they're not in the team.
