REVEALED: Arsenal to spend £40million on German star

A very reliable twitter source Geoff revealed on twitter today that Arsenal wants to spend £40million on a german player. Geoff is well known for his concrete news as he doesn't say what is not true concerning transfers. A typical example is Flamini's signing which he tweeted earlier on before it was announced by any other source. He has refused to say any other thing despite Arsenal fans' persuation to know the german player involved. My first guess is Mesut Ozil of Real Madrid who has been linked with a move to Arsenal for some days now. Who do you think this german could be?
