THE POP-UP PENALTY: HOW DID CRISTIANO DO IT?

1 CRISTIANO RONALDO runs up to take a penalty for Real Madrid against PSG on Wednesday night. As he prepares to strike with his right foot, he plants his left foot next to the ball.

2 THE force with which he stamps down with his left foot disturbs the turf under the ball, causing it to pop up.

3 WITH the ball off the turf, Ronaldo effectively volleys the penalty into the back of the net to make it 1-1. Real go on to win 3-1.
