I think it is the same if you were to say "this poker is non-sense. I had two aces but my opponent won with 2 and 7 "

Dude, you most probably did everything correctly, just got unlucky... in those cases I always recommend and do myself - just go very aggressive tactics to force a win, so that the upset wouldn't happen. Once against a very weak team (-40%) I lost a match 0-2, but then I go beserk and next match I won 6-0. And belive me - in reality stuff like this happens even more often that in top11.

I've told before and I will say it again: TOP11 is much more consistent than real life. It is the fact that we play two matches everyday, we are prone to see upsets more often than our beloved teams.
