But this is football, just as Barcelona managed to lose to Monaco which they shouldn't have lost, and just like how Bayern managed to lose to Villa which they shouldn't have, then we can assume either of these teams could win their games as well, there isn't really a way to calculate which team is better based on a single game. Kompany is definitely more inexperienced, we know this as a fact and Flick will definitely use this advantage to do what Kompany doesn't expect them to do.
We can’t picture it in that manner as you’ve just said. This two teams are big teams in the champions league and there’s no season they don’t qualify and play in the champions league. Even without the coaches, both team players already have some substantial experience of the competition already. We cannot say that Hansi Flick will win the match because Kompany is not ready to face such a big team like them yet. But yet, he is just coacchin the big team Bayern Munich for the first time and he’s making a good record already and placing the team right above every other team in the league. I just don’t feel this match will be easy for any of the teams to win, they’ve to put in that extra effort before they can win the match.
