This was an unexpected result. Surely a lot of gamblers lost money in this match. Naturally, we considered Bayern Munich as the favorite in this match. Because Feyenoord is not considered a very strong team. Feyenoord is a mediocre team.
Bayern Munich dominated the match. Bayern Munich players had 80% of the ball possession. However, Munich's defense was weak. Feyenoord players attacked too much. However, the team was more focused on scoring goals than counterattacking. Feyenoord players were able to make several strong counterattacks and the team was able to score goals.
Feyenoord was very tactical in this match. Feyenoord played a somewhat defensive strategy. On the other hand, Bayern Munich played a completely attacking strategy but could not score a single goal. This was a big failure for Bayern Munich.
I must say Bayern Munich defense far from what it was before to be honest, this is an obvious fact.
Anyway I think the beat way to defeat bigger teams is with a good defence and a good tactics whereby if the underdog can maximise their chances can get a win or at least a draw against any top team. Feyenoord pulled this off all eyes will be on them in their next match though which is against Lille, the two teams are a dangerous one as an underdog in this tournament.
I saw only the outcome of the game and I was shocked by the result with a lot of respect to Feyenoord which are safe right now from direct elimination at least.
The other game that surprised me is the one between Manchester City and PSG, because the number of goals received by Manchester City exactly and because of City risking to be kicked from the competition if they fail to win in the next match.
Terrible performance by these two teams and I hope they could reach finals in this new version because it doesn't look to be promising..
