Yeah Bayern Munich isn't in a good situation, they need to win all the matches and at the same time hoping Leverkusen will lose at least 3 matches or draw for 6 matches, which looks high unlikely.
Sadly Tuchel joined Bayern Munich during Leverkusen's prime, he need to bear all the criticism since people thinks he's the reason why Bayern Munich "might" lose the title in this season. But Nagelsmann made a good decision to leave Bayern Munich lol.
In terms of strength, Bayern Munich is quite strong and I don't doubt that they can win the remaining Bundesliga matches this season.
Apart from the downturn they are currently experiencing, I also think this is Tuchel's bad luck when he manages Bayern, on the other hand, Leverkusen is quite impressive so it is quite difficult for Bayern to compete with Leverkusen.
Currently, the management that fired Nagelsmann and Tauchle is the cause or person to blame for Bayern's downturn this season.
Considering the squad and quality of players at Bayern Munich, I think it's absolutely possible for them to win their remaining fixtures in the German Bundesliga at the end season but one thing I know will be absolutely difficult for them to achieve is to get past current league leaders Bayer Leverkusen who are currently eight points better than them in the German Bundesliga standings. Thomas Tuchel's men failed to maintain positive consistency from the start of the season while current league leaders are still unbeaten in the league till this very moment and if Bayern Munich can win their remaining fixtures in the league, I think the current league leaders Bayer Leverkusen are also capable of winning their remaining fixtures in the league to make sure they're crowned German champions at the end of the season.
Xabi Alonso's men have been simply unstoppable since the start of the season and I don't think they'll want to lose their focus now that we're getting to the final weeks of the season. Bayern Munich who have dominated and won the German Bundesliga for the last 11 years I think will finally settle for a season with the German Bundesliga title because Xabi Alonso is trying to prove something to the footballing world by ending Bayern Munich's dominance.
Because of how Xabi Alonso have significantly improved the performance of Bayer Leverkusen, he's currently being scouted by many of the top clubs in Europe for a possible transfer to their clubs including the reigning champions of Germany Bayern Munich who also happens to be his team's biggest rivals for the German Bundesliga title this season. The young Spanish manager is yet to finally make public of where he desires to be by next season but should he decide to leave Bayer Leverkusen, I think he'll definitely want to sign for Liverpool as Jurgen Klopp's replacement. But before any possible move away from Leverkusen, Xabi Alonso is currently more concerned in helping his team win the German Bundesliga title at the end of the season.
