Barcelona defender Pique: Real Madrid's Ronaldo the perfect player
"I like the fact that Ronaldo won and cried. It really mattered to him," Pique told Jot Down.
"He had suffered a bit and that's why he reacted the way he did. He's known as a tough character, for being superior in both a good and bad way.
"If I always speak well about Cristiano it's because I like him. People can draw their own conclusions from the gestures and comments, but they don't know. I must add that he's changed a bit recently. He helped me a lot when I joined United."
Pique added: "Cristiano is the perfect player, a born trainer who always wants to improve. He can shoot with his right foot, left foot, from free-kicks, penalties and with his head. He's the perfect player. He's the most demanding with himself."
