Bayern Munich always poach top players from other clubs to weaken the competition, they can easily win trophies if the strength of their rivals is successfully weakened. Bayern Munich always uses a similar strategy when there is another team that is considered their toughest rival, they also made an offer for Xabi Alonso to replace Tuchel, but they failed to poach Alonso from Leverkusen. The chances of Bayern Munich winning back the Bundesliga trophy are very slim as Leverkusen is still their toughest rival.
Although the situation is true, I don't believe it will have an impact when the competition is running. Bayern Munich every season is always identical with the transfer of good players at a high price. Last season H. Kane. This season who? and what we have to know, last season's experience itself justifies what I said that in the competition to win the championship trophy, what Bayern Munich management did was unsuccessful because they lost to Leverkusen. This season we also can't be sure that they will be able to win the Bundesliga trophy because the Bundesliga will only start or will only start on the 24th.
The situation in Bayern Munich team last season proved that something was lacking in the team despite the signing of Harry Kane so if they try to do a good job in the transfer market as they have always done it will help to transform the performance of the team and it will help them to move back to the top level where they will find it easy to challenge Bayer Leverkusen and reclaim the top spot from them. Yes I agree that the Bayern Munich team had an unsuccessful season last season as they failed to lift a trophy after making notable signing but they have a great team right now and a new young manager who is expected to make a different this new season so hopefully they will eventually win the domestic league and get better in 5hr other competitions with the quality they have got so far.
