But if Thomas Tuchel have done a masterful job in taking Bayern Munich in a different level game and with that intention of getting Bayern Munich capable attacker let's just hope he gets what he needed and landed Bayern Munich in the top of the Bundesliga next season and landing them with the Championship league aswell then Thomas Tuchel will be another coach that led Bayern Munich to the championship league again, because back on season 2019-20 now it is almost 3 long season that Bayern Munich landed their championship league trophy,
I think it is asked way to much from any team in the world to expect them to definitely win the Champions League. Manchester City was probably the best football team in the world in the last 3 years or so and still they only managed to win the Champions League once in the last season and even then it was very close against Inter in the final. To really win this trophy you don't only need to be the best team, you also need the right timing and also some luck of course.
I am also very interested to see the "new" Bayern Munich in the next season under Tuchel. So far they have not made any big transfer this summer (though Min-Jae Kim will probably come) so they still have a lot of work to do in order to give Tuchel a proper squad for the next season.
Actually, I find it difficult to say what the best club is, whether it's those who can win a lot of trophies in one season, or those who can win the Champions League, or those who are consistent every season or something else. Because in my opinion we all must have our own assessment of which club is the best version of us. But let's say last season Manchester City were the best club, they have a consistent performance, won the treble winner with the Champions League trophy that managed to complete it.
I agree with you, that winning the Champions League title is not necessary to be the best club, because sometimes there are other factors that will make a club successful in the Champions League.
