I hope it turns out as you say, and Bayer Leverkusen remains in the title race for a long time. We need such a race in the German league. Watching the German league wasn't fun in the years Bayern Munich won the league single-handedly, but the year Bayer Leverkusen won the championship was truly a joy to watch. I hope they do the same thing with their new manager.
You made interesting points mate. Leverkusen under Xavi Alonso was a terror to Bayern Munich and that made the Germans bundesliga once again interesting to watch as it was no longer a one man show as it was for many seasons. So if Leverkusen has to lose form this season and give a lower performance from what they gave last season then the bundesliga will be back to it's boring one man show league again, and this isn't what we wish to watch this season.
