Ronaldo's face tells it all: Juve behind after Demiral concedes penalty
Porto striker Sergio Oliveira put his team in front in Turin after 19 minutes when he converted a penalty conceded by Demiral for a foul on Taremi.
Demiral made a big mistake in the Juventus box. Taremi, with his back to goal, was brought down by the Turkish centre back from behind.
The referee pointed to the penalty spot and Sergio Oliveira had the chance to score. He is a penalty specialist and he made no mistake.
He kept his cool to send Szczesny the wrong way and give Porto fans believe even more that they would make the last eight. As Porto won the first leg 2-1, the goal meant Juve needed two goals to force extra-time.
Cristiano Ronaldo could not hide his disappointment and he was caught by the cameras with a very sad look on his face.
