Its a tough situation to bet on but at the end of the day it's all speculation and I think it would be a shame if this big match was left without any betting on it. I personally might bet that this match will probably end in under 3 or maybe both of team to score. But on the one hand this is also risky especially when looking at the statistics and h2h of the two teams, especially for Barcelona who could not score even 1 goal in the last few meetings against Bayern, it will still be a little risky too but I will try this.
H2H can be a picture for us as bettors what to do but their past will not give the same results in the present with the current conditions of the two teams which are different in the sense that they are coached by new coaches for each team this season and both have shown positive results in their domestic leagues.
I assume the Blaugrana will not be humiliated again like before. They can score goals, another possibility is to win even though on the other hand Bayern also has the same chance but in the end if we have to determine the best option bet, maybe bet on both teams scoring goals, at least more than 2 goals I put a score of 2-1 in the prediction for both sides because I doubt the draw at the end of the match.
