Currently, their unbeaten record has increased to 50 matches after a big victory against Bochum with a score of 5 goals 2 days ago so this is definitely a record that is difficult to break.
At the moment their targets are still the DFB final and the Europa League on the horizon but a Bundesliga win, even if it doesn't really matter because they've already got the trophy, can be a good morale booster and of course it's a good thing to keep their record intact.
Next week it looks like against Augsburg they will make a few rotations to keep their players from feeling shortchanged especially in the next 2 weeks they will have 2 finals so that their treble target is obtained according to plan.
If you ask me the final game against Augsburg definitely matters a lot to Bayer Leverkusen. They have all the season been producing back to back stoppage time comebacks just to keep up their unbeaten record and you think they would want to just let it slip away at the die minutes. I don’t think they will have to rest players for Augsburg Game as it looks clear that Xabi Alonso definitely eyes the unbeaten record which will be the first of its kind in the Bundesliga and since the one achieved by Arsenal invincibles in 2002.
They play more less 3 finals in less than 10 days and seriously I am backing them to win the games comfortably. I see Xabi only dropping players at most in the DFP pokal final due to the team in contention.
