Bayern Munich always been a tough team in Champions League, unfortunately they're in tough bracket since they will meet either Real Madrid or Manchester City in order to enter final round.
It is during the QF draw that teams would know the opposition teams that they would possibly meet on their way to the final, mind you that after the RO16 fixtures are over and we now have 8 teams, there would be another draw, that is when you can know the teams that would face who in the next rounds, but for now that's not possible and you can't know if Bayern Munich would face either Real Madrid or City in the next rounds.
