We need a settled back four, only then we'll get a proper assessment on the qualities of our defence.
It is very early in the season to see, especially with Moreno for to figure, as well as the right back tussle.
As a centre-back pairing, I'd still like to see Sakho and Lovren given a go, at some point, but it will be difficult to dislodge Skrtel for sure. Good ol' Martin seems to rise to the occasion whenever competition is added; lots of love and respect for that!
Sakho will get games of course, and he now knows what the expectations & demands of the EPL are; The trouble is, at times (and only at times), it's a case of "built like Tarzan, plays like Jane" with him.
I'm sure he'll come good, and we'll need quality in this area over a long long season that's for sure.
