One Big, Happy, Circle Zhirk!

I really wasn't going to touch this topic... mainly cause I don't really know much about Yuri Zhirkov. I mean I'm sure he's a nice guy'n all and I'm sure he loves cold winter's just as much as the next guy... so then why has he moved to a club notorious for plunging talented midfielders (other than Lampard) into the depths of obscurity?
