I don't think there will be a favorite in the match between Bayern Munich and Barcelona because Barcelona can get surprise defeats in some matches. Bayern Munich is also going through a very good process this year. Don't let the draw in the last match fool us, they played very well. Frankfurt saved many positions with their goalkeeper and they caught the equalizer in the last second. In such a game, the dominant Bayern Munich confines Barcelona to its own field. This match has a chance for both teams to win.
As per the odds. There is no club being favored to win the game easily. This is because Barcelona is well assembled by Flick. It's different with their opponent, Munich, which is coached by an inexperienced coach. This may be the reason why there is only a slight gap in the odds owned by both teams.
And i think that will be very wise to take BTTS instead of 1x2, i meant, i believe both of the clubs will score. They will play openly in this game, and i predict we may see at least more than two goals.
I think both teams scoring is actually a sensible choice for this game.
