The odds for double chance are like below. 1.56 is quite nice for Real Madrid or draw. I feel like Real Madrid won't lose home at least but it is hard to predict whether it would be a win or draw. I'm closer to draw though but double chance would be a little safer but still a risky bet of course.

Because this match will be tough enough that the two clubs will meet early, so whether the double chance bet will be better than the 1X2 bet or both teams score.
I am quite confused because it is difficult to predict, but I think this bet will be more likely to win even though it is risky because it is a bet so the risk will always be there.
Haven't decided which bet to choose yet, but who knows the bookies change the odds because there are a few league matches they have to play.
