Last season Leverkusen also put their focus on two different competitions even though Leverkusen was only able to win the Bundesliga and not the Europa League. And for this season it will actually be the same even though the competition is starting to be a little different because it is the Champions League which is very competitive for any team. But I am still quite sure that Leverkusen is able to have a better focus and can even be considered a candidate for champions this season in the Bundesliga again.
Bayern Leverkusen played well last season after winning Bundesliga, DFB Pokal and reach the final stage on UEFA Europe League although have defeated from Atalanta. I think Xabi Alonso have good tactician after success winning two trophies from Bundesliga and DFB Pokal Cup and seems in this season will play well indeed participants on higher level competition at UEFA Champion League.
Bayern Leverkusen keep favorable team for winning Bundesliga trophy in this season after some top players signing and not difference drastically between main or substitutes players, its important thing exactly with Champion League adopt new format and have many matches than old format but Bayern Leverkusen squad keep balance.
Almost 100% old squad last season keep defend make Xabi Alonso easily adapting his tactician, for several news players I don't think difficult for adapting because most of them have been training more than one month and not get problem how game play from Bayern Leverkusen.
