I am very rarely trolled. The thing happens like a pattern when I face a certain kind of opponent. Typically, a level -1 team 25-30% weaker than me when I play a crucial cup/CL game (semi or final). This team is not only going to beat me but it's going to deserve it without any reason (my tactic looks better on paper, my team is better, I am present and the oppo is not). I lost 6 trebles in 7 seasons like this. The funny thing is that I later faced two of these oppos in league (of course, at the same level) with the same quality difference and I won easily the two legs. This never happened to me in the old days. I'm sure it's been implemented.
