The rates for Dortmund are not bad and I think it is worth taking the risk and betting on Dortmund for this game because we know Dortmoundisnot stable team and they usually have unstable performance in the Bundesliga but the rate for this team is currently 2.11 and in the last meets they had, Dortmund won the game three times while Freiburg won two times.
Dortmund has a 50% chance of losing or winning
Taking into account the fact that the odds are 2.11, this is a value bet since the profit exceeds the risk 
Overall, this selection looks good, but I wouldn't add it to multi-bet odds.By the way, the odds for Bayern to win the game with Bayer are quite attractive:
1.64 - 4.90 - 4.30
Bayer is on the rise, but it seems to me that they will not be able to oppose anything to Bayern.
