Since Kompany joined Bayern Munich they were having better performances than last season when Tuchel was working there you saw in the game against Augsburg they had an epic performance against this team and they won the game with a 3-9 result while as you said Augsburg was under pressure by Bayern Munich in the second half and to be honest Kompany did his job well and I'm sure in the time between first and second half he talking with players and made them have this good performance and Kane is lucky to play in this team because was the player who scored all the three goals for Bayern Munich.
Their good performance actually has been within their domestic league but in the champions League they have not had some really good performance but they are trying to get some experience in the champions League because obviously they aren't experienced enough and they aren't even a regular appearance in the champions League aswell. I'm hoping Bayern maintains this performance in their domestic league and also the champions League.
