There are some fans who do not want to lose in any way. They want to put themselves above in any way, especially if they are a supporter of a good team. They think that their team's loss means losing their own respect. That is why they make excuses and keep saying them after the loss. In my opinion, it is normal to lose in sports. Even a big team can lose to a weak team because during sports, any accident or good opportunity can be used by any team, which will not always be in the favor of the good team. If the favorite team loses, it should be considered in a normal way without giving any other excuse. In any match there may be some mistakes of the players, but having the attitude of accepting defeat is not bad.
Usually it is a fanatic fan or a newly emerged fan, old fans in a team are more mature in accepting defeat because it is very common for them, while new fans and fanatics certainly don't like it and instead they attack by making unnecessary taunts to their own team which should not be done by fans.
We as fans must continue to support whether we lose or win against our favorite team because with that our team will continue to be enthusiastic about achieving success every season.
