They don’t hate Bayern Munich they are just bored of seeing one team win the league over and over again. It seems no team is up to the task yet but their recent performance have been impressive as we do see some teams with the nerves of challenging for the title and i believe in years to come the story will be different.
Nobody hates Bayern people just dislike that they're the only team dominating the league for a decades now and it's becoming so boring that only one team would be dominating the league consistently, and that's why I'm happy with the way Xabi Alonso is handling Leverkusen and if they remain consistent they could become that team that would stand up against Bayern to win the league and stop their dominance in the league.
Dortmund would had done that last season but luck was not on their side and since this season started they've not been very consistent in their winnings though they still remain unbeaten and share similar points with Bayern in the table, the teams i feel would rise against Bayern in future are Leipzig, Leverkusen and Dortmund, i don't think Stuttgart is strong enough yet even though they're currently in the top 4
