A spokesman for the Bavarians has criticized the excessive use of batons on the club's visiting fans in the buildup to a 3-0 win over Olympiacos.
Greek police have been accused of using "disproportionate" force after footage emerged of them attacking Bayern Munich fans ahead of the club's 3-0 triumph over Olympiacos on Wednesday.
Police were stationed alongside the Bavarians' supporters for the Champions League group stage opener in an attempt to protect them from any hostilities from the home crowd.
But television footage emerged an hour before kickoff that clearly showed officers clubbing Bayern supporters with batons at the Stadio Georgios Karaiskaki.
