Bayer Leverkusen is not preparing to challenge Bayern Munich for the trophy next season, they don't have a solid team yet and they are already looking at having their team to be young players that's not possible. Their management has failed to retain their key players some of were sold out but that they were eager to leave the team and the management is not even replacing the sold players how do they want to meet up next season?.
Didn't Bayer Leverkusen just sold their coach and some first starting players, from what i know it takes quite some time to build a good team under a new management, next season Bayer Leverksen has bare chance to compete against Bayern Munich for the title, except for when Bayern isn't going to perform too well, but performance we see from Kompany in the Club World Cup already says a lot about Bayern Munich performance next season and how they will dominate the league.
