If you are thinking that Erik Ten Hag will sign players and build Bayer Leverkusen to challenge Bayern Munich for the Bundesliga title, I think you are mistaken because when it comes to signing good players, I think Bayern Munich has a good advantage over Bayer Leverkusen because Bayern Munich has the money to splash to get the quality players they want. For the fact that Xabi Alonso left Bayer Leverkusen and Bayer Leverkusen sold some of their good players to other clubs, I now see Bayer Leverkusen as a club that can finish in the top four next season.
Erik Ten Hag now has the chance to prove the critics wrong about their perception of his football tactics, though the bundesliga is not as strong as the premier League but there's still the likes of Bayern Munich and Borussia Dortmund whom will always be there to contend with bayer Leverkusen, perhaps he might build a strong team that would probably replicate all the achievements of Xabi Alonso, because he cannot afford to fail in his new assignment.
