Dortmund vs Leverkesun will be a high intense match given to the fact that Leverkusen are inform and they have currently won all straight eight matches they have played so far including the one against league leaders Bayern Munich. With the rich history of Dortmund and their performance at home, this promises to be a tough match. I will be staking on Dortmund to win the match with both teams to score.
Trying to predict who will win that match might lead to mistakes because both teams are good and either of them can win. What I feel is certain about the match is that goals will be many and both teams will score at least one goal. Going by that, playing both teams score or over 2.5 will be a conservative bet unlike playing any of them to win. But if I just predict who will win, I think that Borussia Dortmund are in in better shape to win the match.
What you said is absolutely right, at the time of the match between elite clubs like this it is better to bet on the total Asia or BTTS because choosing one of them to win is too risky which is certain that the match will cause high tension both teams want to win especially Dortmund who are playing at home of course do not want to disappoint their fans, if I were to predict I think Leverkusen will win this match considering that Leverkusen previously beat Bayern Munich when playing at the Allians Arena (Bayern's home ground).
