Define "world class" defender. It's an awful term, particularly when you take into account that the so called defensive elite aren't actually particularly good at defending. See Alves, Maicon and centre halfs like Ramos and Luiz. To answer the question under a different broad tag, then yes I would. He defends well in practically every game. He rarely gets beaten 1 vs 1, is unusually good in the air for his height, we seldom concede goals from down the right side. I'm not entirely sure what more he has to do.
It's bad enough that the media still maintain stereotypes about some of our players, but when some of our supporters do it then it gets a bit much.
