Assuming you are among those that plays Bayern Munic to score over 3 or 4 goals every weekend but stopped when they were not performing well, this weekend would have brought you some sort of regrets. I know some guys that plays Bayern Munic and PSG on goals every weekend since many seasons ago and they have made fortune from gambling. This actually made me come to the understanding that someone can actually develop a gambling strategy that can help improve the chances of winning.
Bayern Munich managed to score up to eight goals because the opponent they faced was Mainz, where it would be easy for them to win because Mainz is a team that has no enthusiasm to compete again. Mainz's position in second place means there is no chance for them to get back up. At least gamblers can grow their assets easily because they saw Bayern Munich win this match.
