A similar situation happened last weekend, BVB playing Gladbach. Gladbach was behind with a goal, and the goal keeper made the way to participate in a corner kick in the extra time. Dortmund managed to win the ball while the goalkeeper was still out of position, the BVB player managed to run the ball towards the empty goal and score the 4:2. The ref did not end the game but let the situation play out…
The penalty was a joke like many other hand penalties this season.
Anyways I will be rooting for AC Milan to book the ticket for the next round, no sympathy for oil money clubs.
