Per Mertesacker isn't a big fucking German. He's the Big Fucking German.
So maybe Chris Lymberopoulos shouldn't have gone on air with the nickname that is normally restricted to Arsenal pubs and the Clock End at the Emirates, it's not like he's wrong. At 6'6", 200 lbs., Mertesaker is a big fucking German.
And it's not as if Mertesacker takes offense. In fact, he happily promotes the nickname, at least when it comes to selling shirts for his charity.
That may be a little too unofficial for some. After all, why get a t-shirt when you can get a kit.
