As you said, I often see big clubs losing to clubs that could easily be beaten on strength, but the fact is that in pre-season matches like this, it becomes more difficult. They end up with a lot of draws or even defeats.
I don't deny that I sometimes think about betting on pre-season matches, especially when I have more money to gamble with. Talking about the chances of winning, then it becomes lower than we bet on the same competition, maybe I don't have to say what the reason is for me saying that, because I'm sure we have the same thoughts about this.
They don't look at the final result, what they look at is how they play, and also they don't play the main players full time, but also give young players or players who rarely get a chance to play (second-tier players) the opportunity to be on the field.
All the main players and second tier players have their place in preseason matches like this, so it's not surprising when in the second half their players completely changed from what happened in the first half. So, there is no target to win in a match like this, they just take advantage of the opportunities they get to score goals, but the target is not to win. So indeed, betting on prematch events like this is a very risky bet, because whatever predictions you make don't seem to work at all. But indeed, after all betting is also about luck, so if you keep betting on events like this and then win. So of course you might be said to be a very lucky person.
Or even matches like this will be a place for players who don't get many minutes to play to show their abilities and be glimpsed by the coach to be part of the starting line-up later, it's a very possible thing. But until now I rarely see any players who can penetrate the main place from pre-season matches like this, it's not that there aren't any, it's just that we rarely see it. Apart from that, young players can also show their skills in order to break into the main squad, although they may not play the full 90 minutes, but usually they will be substitutions that will bring new colors to the game.
