I'm seeing Bayern Leverkusen winning the Bundesliga League Competition again this new season honestly. I don't have much comments to give on Bayern Munich, they'll have to prove that they've got this and wants it.
At least, even if there are players leaving Leverkusen, there are indeed some rumors, Leverkusen has also started signing to strengthen their team this season for tighter matches and competition. Recently, they signed Martin Terrier.
