Leverkusen has been receiving financial support from Bayer the pharmaceutical producer for a long while now. That is why they could afford above average salaries and they are also a team that is popular by young players who want a club where they can play and develop further and then take the next step. For Xabi Alonso these are good conditions as it seems that he has a good connection with younger talents and at the same time he can build a quality team since they don't have to let all the talented players go every year. Years ago Leverkusen has been a strong rival for the top four and I think Alonso can get them there.
Bayer Leverkusen is one of the best club in Bundesliga and their finances and talent project are also helping them for having better results even in last season they were badly down and out but management done good decision at right time and have coach like Xabi Alonso which helps them for having dream end of their season even in last few matches they were badly down and lost the chance for the higher place but still it's good end for them in both events with losing against Roma was also interesting because they have done good job in this semifinal.
Now Xabi Alonso is understanding all which is surely going to help him for having good strategy which helps him for having better end of this season in both events with some big trophy can do good magic for them as well.
