Their defense is a threat to themselves, because we know that they have not been able to make their defense more solid, and in fact it happens every season, it's just that it's covered because they can create more goals than the number they concede. This season will be a different one as they are working with a new striker. And once again we see an obvious weakness in their defense after they lost badly to Lepzig in their Super Cup match.
Either way, Tucel will have to quickly solve his problems within the squad, as it's a very vulnerable position.
Tuchel needs to strengthen his team's defense before the start of the season. He has to come up with a change in match strategy. If the defence is not strong, the team may lose dominance in the Bundesliga.
There is no doubt that Werder Bremen is a weak team. Munich is more likely to win this match easily. But if Bremen somehow manage to score the first goal of the match, it will be very difficult for Munich to win this match. Because, if Bremen can score the first goal, then they will play completely defensively. All 10 players of the team will play the role of defender. It becomes much more difficult for any team to score when the opponent plays defensively.
If a situation like this happens, then it will be more difficult for any club to score when the opponent goes down with a "parking busny" strategy, including Bayern Munich.
