Even if Bayern Munich couldn't get good results from their previous matches, it doesn't mean that they will repeat the same poor performance against PSG in Allianz Arena. If PSG wants to make the match dull, it means that they accepted defeat whole heartedly and that will give Bayern room to score as many goals as possible.
On the one hand Bayern will never dull the match because Kompany wants to use this match to start back his winning streak and end the recent poor performances.
Yes, Munich will definitely dominate. The previous bad results were obtained when they played away, and later when facing PSG, Munich will play at home. It will not be easy for PSG to get points.
Even if they do not win by a large goal difference, I am sure that Munich will be superior to PSG even though it is a narrow victory because PSG could do a strategy that Munich would not expect.
