Leverkusen under the guidance of Xabi Alonso has performed very well. I am sure that last season neither the club nor Alonso targeted to win the Bundesliga, but as the competition progressed, playing match after match with victory, in the end they worked hard to try to break the dominance of the German League giants. as we know, they were able to make it happen. in the Champions League, although it can be said that there are many strong teams, especially with the new format. but I am quite sure, their determination and desire to play as well as possible are very great. at least, they will try to qualify in the group phase.
In the match against Hoffenheim, the squad coached by Xabi Alonso was able to return to winning ways, overall they performed well. so did Boniface, he started to score goals again. although, we know their opponent team is not a very tough team. however, returning to winning ways is part of their progress and plan in this competition. besides that Alonso knows very well that he will always correct his team, especially if their performance is not playing well.
IMO, repeating the success of winning the Bundesliga trophy seems quite difficult to achieve.
