When Tuchel joined Bayern Munich he never had enough time to build the team and show his true performance, also many people stated to blame Tuchel because he lost the champions league in the next season they hired Tuchel mostly because of the champions league while we can't complain because Tuchel didn't have enough time.
But in the next season, Bayern Munich can buy the players he needs and he also got the time to rebuild the team for the next season, I think if everything goes well we can see Bayern Munich winning the Bundesliga title easier compared to the previous season.
Thomas Tuchel doing good work in short time and right now Bayern Munich is surely having good performance with just missing aggressive striker which is taking time with most chances we will have good news about this before start of the next season and if this all happens as requirement then surely things could be into their favor and most chances they could be team to watch in Champions League as well.
Currently, there all players are doing good job, and they are surely feeling better than last season which was surely miserable now in coming season their main target is Champions League with Bundesliga is still easy title game for them because in this league we have no good side which can give them good fight for the title race.
