Derby v Chelsea: Steve McClaren finds no flaws in Chelsea

Derby manager Steve McClaren says he can find no "weaknesses" in Chelsea's squad ahead of their Capital One Cup quarter-final against the Blues.

Chelsea won 2-0 at Derby in the third round of the FA Cup last season and after strengthening their squad in the summer McClaren knows this will be a tough test for his players, adding they will have to be at their very best to come close.

McClaren goes on to recall the first time he faced Jose Mourinho as a manager, describing it as a "nightmare."
