You’re all narrative merchants who want to attribute essentially random events to something more solid, as you think the sport you love is somehow devalued if you admit it wasn’t all destiny and that if the ball had bounced 10cm in the other direction one time, a team in blue would be lifting a trophy instead of a team in red.
So even when team A batters team B, hits the post eight times and then concedes a last minute deflected winner, they weren’t unlucky, but Team B had a better mentality, or Team A’s manager always bottles things in Europe so this was inevitable, or it was actually the genius of dropping player X into a false 9 rather than playing a traditional striker that made the difference.
The fact the best team doesn’t always win is what makes football interesting. Winning any big cup competition requires being both really good and really lucky. People should embrace that.
Regardless of luck, the best rises to the top. Take Cups, the teams know as the best win it 99% of the time. And with leagues, the best team that season end up winning.
There is luck on a match to match basis but over the entire course of the season, they usually balance out.
