......It's just that once again it will depend on the club and how they can anticipate this, that's why there is a transfer market where of course Leverkusen also have to consider the strength of who is leaving and coming, between players who are leaving and arriving. And for Xabi, he also has to be able to adapt to a squad composition that may be new, although not all of it, but with several new people and several old people leaving the club, of course he also needs adjustments to implement his tactics as well as last season. Then, we can only entrust this to Xabi.
In the last season, Leverkusen was incredible right up to the final second.
Yes, they lost the final in Dublin, but the journey will last forever. There may never be a season like this again, but Leverkusen is there.
This season, Leverkusen still is one of the top contenders to win the Bundesliga next season
Bayer Leverkusen currently has more than a 60% probability of winning the Bundesliga. IMO
Xabi came back home to recharge his batteries and left with a bomb, that shook the world 
Of course, this will be the first history that Leverkusen has achieved and it is truly amazing, full of surprises and incredible. How could it not be, they were a mediocre club before even though they had entered the UCL, then suddenly they were so overpowered, unbeaten in the Bundesliga for a season, and almost unbeatable throughout the season, only losing 1 in the UEFA Europa League final. And their hope is that specifically in the Bundesliga, that won't be the only record they break, especially if they can continue. But it won't be that easy, this season will be much more competitive. Bayern Munich and Dortmund in particular will be more serious than in previous seasons.
Oh yes, if Arda Guler really goes to Real Madrid, this will be a pretty good addition, right? I read the news regarding Real Madrid opening up a loan opportunity for Arda Guler. Leverkusen was one of those who was immediately interested and if I'm not mistaken, they had been looking at the winger for a long time. Hopefully this really comes to Leverkusen so they can strengthen their front line even more.
