Borussia Dortmund fans used banners before Saturday’s Champions League final to protest against the club’s controversial sponsorship deal with German armaments maker Rheinmetall. “Rheinmetall – football’s clean-cut image?” read one banner before the match against Real Madrid. The three-year sponsorship has been criticized across Germany this week. According to Dortmund’s incoming head of sport Lars Ricken, the deal was “not an issue at all” within the club. There had been “zero distractions” before the Champions League final, Ricken told ZDF.
