Uncle Speilberg has a source at the club, hopefully (when US takes a break from the new Daft Punk album) he can furnish us with some info. The is definitely something going on with this TANK fella.
Just been researching him. He was a recent top-flight coach in Japan and was also at Cologne a couple of years ago. I heard that the connection is the German club doctor. Left field or are we just ignorant of other leagues?
He has been coach/assistant at some German clubs and in Japan I think. Quite a forward thinking chap by all accounts; I guess he might have picked this up in Japan like Wenger did.
