He's not as dominant during defensive set-pieces as he is during open play, but he's not as bad as some make out. He uses his arms a fair bit but then so do plenty of other defenders, and he's been penalized for it what, once or twice in his entire career? It's obviously not as big a deal as many on here make out. It also has to be noted that he always covers the oppositions biggest threat, so invariably he's given a much harder job than anybody else in those situations. So yeah, he could be better in that regard, but the fact that he's still comfortably our best in those positions show how much we rely on him.
