The whole problem of Borussia Dortmund is precisely that their results are unstable. After a good start to the season, they often have a strong decline in the middle or at the end of the season. Very often I notice a situation when a team has a lot of injured players. What could be causing this? Most likely because the team plays attacking football, which already puts players at greater risk on the field.
Because they build up their team with young players and they can have very good period but if they have some bad results, they will slip very far. When they are able to balance their mentality and back to good results, it is too late for them. Because in Bundesliga, Bayern is very strong and stably grab 3 points from their matches.
It was an entertaining half, even better than the first. Bayern's defensive problems lies in the fact that they're missing a leader at the back. The sooner a new leader emerges, the better. But on the attack side, they're doing very well. Just need to improve their defence more. Cologne showed that, with good attacking plays, you can take advantage of Bayern's defense and cause a significant amount of damage.
Bayern lost Alaba and the new defense system need time to work together. Their defenders are good so they will fix their connections for the defense system after a few real matches and more trainings.
Problems in Bundesliga is Bayern can win many matches and one or two defeats mean nothing with Bayern. Final result is they take the Bundesliga title.
