Perhaps I should not feed the troll but..... I don't see what the big deal is about EPL defenders. Why does one automatically assume they're better than everyone else.
Terry? Showing his weaknesses now that his stronger CB partner (Carvalho) is gone. Slow and rather poor at defending set-pieces anyway. Ferdinand? Was quite good a few years ago, but showing his age. Vidic is good, yes, and the one off that list I actually rate as 'very good'. Vermaelen? As stated, poor positional sense.
I'd rate Walter Samuel, Lucio, Vidic, Chiellini, Silva, Carvalho, Pepe, and Nesta as probably the best currently playing for clubs other than Barcelona. Pique and Puyol are IMO probably the strongest CB pairing right now at bot club and NT level. Pique is very, very good, though his positioning at times could improve (this will come with experience).
