Just for the record I want to say that Mertesacker isn't a sack of shit, I'm just angry because he's not my kind of defender at all. In the box and doing most of what a centreback has to do, Mertersacker is very good, but he is the slowest defender I've ever seen, and he does have no balance or agility at all, I have a big problem with that, and I also think he's a big, giant pansy too.
But I'd rather him than Djourou and maybe even Koscielny.
