It's true that Leverkusen's players worked hard. Also Xabi Alonso's match strategy was excellent. And because of Alonso's match strategy, Leverkusen team was able to maintain the winning streak. Xabi Alonso is undoubtedly the best coach this year.
Every player must work hard, it is the responsibility of every player in a football team. However, I can appreciate Leverkusen players, they could understand well the tactics or strategy implemented by Xabi Alonso. They also want to force themselves to play in a higher level, so they can be more competitive. Besides Xavi has a smart idea for the team, the spirit among the players also has a big role to make them be a stronger team in this season. Anyway, I can admit that Xabi got a great achievement with Leverkusen in this season.
Leverkusen's players were confident. Also the players were hard working. And Xabi Alonso was the mastermind behind Leverkusen's confidence building.
Xabi Alonso's match strategy was very good. Xabi Alonso used to make match strategy considering the strength of the opponent. This is why the Leverkusen team performed well in both matches against Bayern Munich. There are no star players in the Leverkusen team. Still every player gave full effort from his position to do well. All this is possible because of Xabi Alonso. He has taken a mediocre team to extraordinary heights, which is why Xabi Alonso is the best coach in Europe this year
