I've thought that he's been severely underrated for a while now. IMO, not only is he our best CB last season and the best one we have at the moment, but a top 5 CB in the world and maybe even towards the higher end of that list.
Look at how hard his job is out there, it'd actually be 100% understandable for him to mess up every now and then. But it simply doesn't happen. He rarely fucks up at the back compared to other CB's. I actually can't believe it's possible for him to defend that well given how much he constantly has to defend.
AND on top of that he was making slicing passes through multiple lines way up the pitch, finding Deulo/Suarez etc. He always does it and, though he doesn't opt for aerial long balls he is a master of long ground passes and through balls and all between lines. Our best defender both on the ball and off it.
