Please avoid making long threads titles. I have adjusted this post for you.
Now regarding your question, I think it was our match against Bayern Munich in the Champions League final. To make it even worse, Bayern got a Penalty Kick.. But we kept on believing and won the match at the end. I know that we were the ones behind but another goal for Bayern would have ended our chances. :)
Name an important match you won by a 1 goal adavntage and in the last minutes you were so afraid that you would concede the equaliser.
