The coach that led Bayer Leverkusen to win the Bundesliga title and made Bayer Leverkusen a threat to Bayern Munich lately is no longer the coach of Bayer Leverkusen, and we aren't sure if Erik ten Hag could lead Bayer Leverkusen to challenge for the Bundesliga title and be a threat to Bayern Munich next season, so we have to wait until the new Bundesliga season starts for us to know if Bayer Leverkusen will actually be a threat to Bayern Munich or not. The Bayern Munich player who was injured in the Club World Cup by the PSG goalkeeper is a big blow for Bayern Munich because he's one of Bayern Munich's finest players, but Bayern Munich is lucky the transfer window is open for them to replace him, so I think Bayern Leverkusen will not capitalize on Jamal Musiala's absence to beat Bayern Munich to the Bundesliga title next season.
Xavi Alonso actually bring leverkusen to space because no one expected a rapid performance from the club, it all happened as a shock to everyone that why they are able to win the title. This season was different because already the knew what they can do that's why Bayern Munich stand firmly to take the lead in the competition and that is how they are able to tackle them down, this happened the following season of Xavi Alonso and now he has left. Erik ten Hag has a lot to do because Bayer Leverkusen have already became a threat to bayern Munich in the last two season and that fear will still be in them because Xavi is not the coach but he has built a team that have team work. Erik ten Hag shouldn't be underestimated because of what happened in Manchester United, definitely he had learned a lot from his past and when he tried to implement it here you will definitely be tougher than Xavi Alonso.
