2 years ago or so, I won the cup first leg vs an about equal Q opponent 6-1 at home just to get defeated 5-0 away in the second leg. It was the craziest thing ever happening to me in TE. Since then, I am never sure to be through to the next round, as anything can happen in this crazy game... I wonder how there can be such a high spread in the possible results and then two extreme results are triggered one after another.
