People think Xabi Alonso is the only reason for Leverkusen to get good results and that's totally wrong, Xabi Alonso is definitely a good coach, and he had an effective plan since he started working on this team.
Maybe without Xabi Alonso, they could never get the results they got so far during this season but the fact about Leverkusen is about the teamwork and I think just like Xabi Alonso in this team, other players and coaches had the same share of their success.
You are very correct, everything can't be accorded Xabi Alonso alone because there's a team behind his success and all this has contributed to the success of the team so far this season but because he is the head coach and if anything goes wrong he will be the first point of call and same applies if anything goes right.
The cooperation of the players, other managers and the team as a whole can't be over looked because they are all contributing factors to the success and that's why I've always been of the opinion that a coach can be good at a particular team and when he moves to another may not do as much as he did with the other team and all these are the contributing factors that helps the coach and the team as well succeed by the end of the season and probably win trophies, conclusively it's as a result of team work the squad becomes even more successful.
