Morata put Atletico ahead, in the old days I would say that Real could be in trouble if Atletico had the same good defense as they used to. But now we can wait a bit and bet Real +1, or Real will score. It will be necessary to look at which event will have better odds. Atletico took the lead a little unexpectedly, but Real Madrid has been missing a lot lately, I think that Real Madrid wont give up so easily, all the struggle is still ahead.
In the end Real Madrid managed to qualify for the semi-finals despite some protests by Atletico Madrid players during the match. I saw both teams trying to win the match, but of course this match was in favor of Real Madrid because at the crucial moment Atletico Madrid had to lose player because of red card. I don't think it was bad foul worthy of red card, but the referee seems to know more about how to make decision even if it could change the game.
After the match, Diego Simeone criticized the referee for his leadership during the match. Diego Simeone considered that Real Madrid should have received red card when Morata was fouled, but Real Madrid escaped. I don't know who to justify, but derby match are often hot.
