Realmadrid almost losed it but anyways they made it even though they had the chance to seal everything once again @70'min..but Vini missed it. Thus regarding the penalty kick, I didn't see a double kick, the media played it over and over for like 5 times and even slowed it , the only thing I saw was a slip and it almost hitted the ball it self , tbh I saw no DK... it is what it is... unto the next phase .I kinda love Simeone rage in the end though 
Real Madrid is something else when it comes to the champions league and I knew Atletico Madrid didn't stand a chance the moment I saw the feature. They've never been sent packing in the knockout stage by Atletico, so I was pretty sure they were going to progress to next round of the competition. I feel sad for Diego Simeone and the players for the hard work and I hope they get better luck next time.
