Maybe what is happening is so much people is putting money on them so the odds are becoming lower and lowers waiting for a surprise.
It sounds funny to me how people give Dortmund a high chance of winning this league title because I don’t see any sign or performance that will convince me to agree that Dortmund are going to win this league, even though we know that the same thing that happened to Leverkusen can happen here tomorrow, but still, I won’t give Dortmund a high chance that they will be the winner of this match. The oddsmaker just did this in favour of them and nothing more than that.
If not, I believe they also know that Dortmund will not win Real Madrid. Real Madrid are fully ready for this match, and I’m very sure they will get this title, so let’s wait and see how it will turn out tomorrow. Since I can see that most of us already believe that Dortmund are going to win the league, we should not conclude on one thing for now. Let's see the result tomorrow.
