Naggelsman explained it even better after the game, which actually points towards a mistake in the interpretation of it, as it should have stood as a handball just like it did in every other match when the same thing occurred, as in the direction of the ball being towards goal and Cucurella’s hand basically translates in him extending his body to block the shot is all you need to call it, regardless of intention, voluntary or not.
“There is a rule and I hope there is no wrong decision. They applied the rule and it was not a penalty. I do not feel cheated. For me the question is about making it more practical, more logical, in terms of how this [handball] rule is assessed. I say this for football [in general] not today. You look at the hand, if it is at 3 o’clock, if it is a bit higher or a bit lower. But there are people with bigger muscles than me, different movements.
I don’t understand why we don’t take into account what is happening with the ball. If Musiala kicks it towards Stuttgart centre and it hits the hand, I won’t say anything. But it was going towards goal. And for me, you should look at where it is going. Is it going into the clouds or is it going in the goal? In one case it is a penalty, in the other it is not. If it is going into the stands, then it is no penalty. The rule should be simpler. You can’t talk about intentions. You have to see where the ball is aimed. We have 50 robots that bring us our coffee so there should be an AI that calculates where the ball is going.”
