Their chances are getting slimmer because many key players have left the club, and even the current manager hasn't offered any significant guarantees for Leverkusen's progress. I doubt they can even compete with Bayern Munich because considering the number of players they currently have, they're not as good as they used to be, making it difficult for Leverkusen to compete. Bayern Munich has improved significantly, and they've made many changes, bringing in a number of needed players, so they'll be much stronger next season. The Bundesliga title race is not much different from Ligue 1, as only one team can truly dominate, and it's difficult for other teams to compete if they don't have players of equal quality.
Beside the facts and changes that happened in Bayern leverkusen there is only wish that they performed well. Because the team with Bayern leverkusen has to compete in a very strong position. While on the other hand the Bayern leverkusen has lost their talented and successful player. I think to compete in any strong team there is a need for a strong club which is only made by adding the skilled and talented player to the club . In this regard the policy of Bayern Munich is quite impressive as they don't stop buying new players and are always in the race to get better and even better. But if the Bayern leverkusen sold their player then definitely they have some alternative plans to perform well because the leverkusen team is a good team they always try to win with hard work and prepare for competitions.
