Bayern Munich prepared for their match with Juventus on Tuesday with a win over Darmstadt at home in the Bundesliga on Saturday.
Pep Guardiola's side did not have it all their own way with Sandro Wagner giving the away side the lead.
After half-time, the game turned Bayern's way as Thomas Muller scored twice and Robert Lewandowski completed the 3-1 victory.
Muller has now scored 17 goals in 22 appearances in the Bundesliga this season.
His second against Darmstadt could well go down as one of the goals, if not the goal, of the Bundesliga season.
