Arguments are on point and I agree fully. Lucky should be involved.
I lost once in the 16th round of the champions league against a team 8% weaker than me. I was annoyed but both managers were there, both games were tough. He won on penalty. That was a respectable loss.
In another season, I played against a team 30% weaker than me, lost 2-1 even though the manager was absent. This is slot machine gaming.
Players should respect all teams, but they shouldn't be praying that their team suddenly plays like rubbish and loses to much weaker teams.
