The Champions League is much more competitive than the Bundesliga.We saw some lacking in the last European game of Leverkussen where they were down at home 0-2 from a team from Azerbaijan league like Qarabag and sure they finally managed to win the game 3-2 yet this shows that they have not yet the confidence needed in European competitions,that comes only with experience.I also agree and enjoy the choice of Xabi Alonso to stay in Leverkussen and try to bring back the glory they had in the 2000-s when they were playing and winning a final against Bayern Munchen in the Champions League,so surely is a great thing that he is staying.
Because next season Champions League is still very far away, Xabi Alonso has a lot of time to continue improving the depth of his squad, even though the current level of stability is promising, the Champions League competition still needs to be double what they currently have. The competition is definitely more difficult and this also requires Xabi Alonso's intelligence in formulating his squad. Leverkusen's entry into the UCL is not only interesting to look forward to, but also motivation for its players to increase their popularity in the eyes of Europe's elite clubs. And now there are many rumors regarding the interest of European clubs in considering recruiting Leverkusen players.
