Xabi Alonso let Leverkusen plays very attacking in this season but he is cleverly to command his players to calm down and reduce playing intensity at a right time within each match if necessary. I believe Xabi Alonso will not let his players go playing seriously attacking and lose control of their minds. It's risky as Atalanta shown in their first quarter final match with Liverpool, that how dangerous they are in counter attacking.
Xabi Alonso, the maestro and his disciplined players were clearly able to control the course of the match so if you pay attention, Leverkusen always attacked in the second half by carrying out quick counterattacks. Foot to foot passes illustrate how calm the Leverkusen players were when controlling the game. Atalanta succeeded in overthrowing a big team like Liverpool, therefore Xabi did not take it lightly, especially in the final where Atalanta had quite solid defense and attack. I still support Leverkusen to extend their unbeaten record this season, after finishing in the Bundesliga they will focus on the Europa League final and then finish in the DFB final against Kaiserslautern.
