Bayern Munich fans threw bundles of fake money on the pitch during the win at Anderlecht in protest at the cost of away tickets for the Champions League match at the Constant Vanden Stock.
Play was briefly delayed while players and officials cleared the money.
Anderlecht charged up to 100 euros (£88) for Munich fans to attend the game in the capital of Belgium.
Bayern told BBC Sport they had discounted the cost of the 100 euro tickets by 30% to 70 euros (£62).
There had also been protests about the ticket prices for the match at the Constant Vanden Stock Stadium during Bayern’s game against Augsburg at the weekend.
Bayern supporters have regularly protested about the cost of ticket prices in recent seasons, throwing rolls of paper onto the pitch during their last-16 win at Arsenal in March.
Corentin Tolisso scored the winner for Bayern after Sofiane Hanni had cancelled out Robert Lewandowski’s opener.
Bayern are guaranteed second place in Group B, behind Paris St-Germain, who maintained their unbeaten record with a 7-1 thrashing of Celtic.
