U will win cl is for the .... Weaker to win I lost against 97-103 opponent
Look at this post - I'm right (black one).
It was second leg away and lost first 0:2 at home. I won 1:3, stayed in the cup and finally won it. So, everything is possible. All you need is a good (counter-)formation and tactic-set. You also have to change tactic (maybe formation), if it's needed. And you need a bit of luck.
