The things is by the end of round 5, I was in 2nd place with the same points of the 3rd place guy, and on last round we both won by 1 goal and he passed to the 2nd place!

If the Goal away counted he should have been in 2nd place by the end of the round 5 aswell

And how come a group phase can be decided by away goal (usually used only in eliminatories), when you have goal scored and goal difference to compare like in all other real competitions? oO
