On Wednesday night, Celtic will hope to record their second successive win on the road in the Champions League when they make the daunting trip to the home of the Bundesliga giants.
However, Sinclair has revealed that the team believe that they can cause a surprise after running out 3-0 victors against Anderlecht three weeks ago.
The 28-year-old is quoted by BBC Sport as saying: "They have so many world-class players that can damage us, but that shouldn't faze us.
"We come here with the confidence and belief that we can get a win. Winning away from home for the first time in many years has really given us belief."
The clubs are meeting for the first time in 14 years, with Bayern claiming a 2-1 win when the teams faced each other in Germany in 2003.
