To be fair, this is not an easy match for both clubs, Borussia Dortmund or Leverkusen and that is indeed the reality. Borussia Dortmund may have the advantage because they will play as the host, but Leverkusen is a club that is in its best phase especially after they managed to become champions last season. Borussia Dortmund must also realize that their current opponent is not an opponent that can be underestimated, as well as Leverkusen, even though Borussia Dortmund is not in good condition, they are still one of the good clubs in the Bundesliga. So I hope they can show an interesting game to watch.
Personally I give my support to leverkusen even if they probably loose the game but now I have more confidence in them possibly winning even while playing from away, dortmund has been too unstable for me to believe they are possibly going to be able to win easily, they will have it tough that's if they eventually does but leverkusen is looking so muof a good contender who isn't going to let any form of advantage become edge enough over them such that they loose the game.
