Davies our worst player? Are you mad? He is probably our most consistent full back now that Walker is gone - Rose still has to prove himself back from his long time out, Aurier has shown very good moments but also very bad moments, Trippier is not good enough defensively but can put in a good offensive performance when given the space to play.
Davies on the other hand is always one of our best defensive players, very rarely gets beaten for pace which is a miracle for a bloke who isn't exactly lightning. Puts in last ditch tackles and covers CBs excellently. Going forward he is aware of his limitations and doesn't push himself to try and take people on down the outside so plays to his strengths and does inside overlaps where he influences the game and lets Son take an outside position to get one on ones. His crossing against WHam wasn't one of his best nights but he is actually very technically sound and can hit a good delivery - not to mention he gets into the box more and has more shots on goal than any of our other full backs.
