N. Amoruso: C. Ronaldo is afraid of getting hit in the face with a ball © AFP

Former Juventus striker Nicola Amoruso has warned the team's coach Andrea Pirlo not to put Cristiano Ronaldo in the wall during opponents' penalty kicks. According to the Italian, the superstar is afraid of getting hit by the ball while running and it causes additional problems. Portugal received a lot of criticism after Tuesday's fiasco in the UEFA Champions League, when Porto's Oliveira buried the hosts' hopes of advancing to the quarterfinals with a penalty kick in extra time. It was then that C. Ronaldo stepped aside, allowing the ball to pass below and later bulge the net. "I would never put him in the wall. C. Ronaldo is afraid of getting hit by the ball in the face and getting injured in his appearance," N. Amoruso told Sky Sports Italia.
