Swiss authorities prevent Real Madrid from displaying Bwin logo

9/16/09 – Real Madrid played its first UEFA Champions League group away game without displaying the logo of its major shirt sponsor, Austrian online sportsbetting group Bwin this week. 
A statement on the football club's website advised: 
The Swiss authorities only allow gambling to be advertised when they are state-owned companies. 
"As a result, and given that Switzerland is not bound to European Union legalization, Real Madrid and Bwin have chosen not to display the logo on the team's shirts during the Champions League match between FC Zurich and Real Madrid."
