I think Xabi Alonso is making good decisions to improve his team before difficult games. He has to be careful about who he chooses because Leverkusen does not have a lot of money. Even though he has done well with Leverkusen I am also worry that they do not have as much money as big clubs like Bayern Munich. But I still believe in Alonso ability to succeed despite these challenges. He is a smart coach who can get best out of his players and that will help Leverkusen compete with the bigger teams. I think he will find ways to overcome financial limitations and lead his team to victory.
The financial differences between Leverkusen and Bayern Munich were proven last season and this fact should still be able to continue Leverkusen's success next season. I think as long as a team can adapt to its competitors who have certainly made improvements then they won't feel left behind either.
Besides, what can we expect from Bayern Munich with coach Vincent Kompany? Isn't that an advantage for Leverkusen because they still have Xabi Alonso and are clearly better than the Bayern Munich coach. If only Xabi Alonso agreed to join Bayern Munich, it is possible that Leverkusen would no longer be equal or even be able to defend their title again.
