There was a brilliant one hour documentary on Wynton's Bremen side winning the German league and cup double on beIn Sport Sky Sport 7 about a month ago.
Titled "My Season: The Werder Double"
It consists mostly of interviews with four members of the side (and Rufer is one of the most prominent) plus footage from games across the season.
Interesting that Rufer is described affectionately as a maverick , a bit different, a bit of a joker in the team, a little crazy.
It's a great story of a coach, Rehhagel, with unique coaching methods, strong on the psychological approach.
He signed players based on character as much as ability and Rehhagel's wife, who was very astute, had a big say on who was signed.
I can't find the documentary online but here is a comprehensive German language one about Bremen's title win:
Wynton's first goal of the season is just 3 minutes in:
