Ronaldo's header has fired the Portuguese into the Euro2012 semifinals.
"The more you talk about Cristiano Ronaldo, the stronger he gets. He is a player from another world. To him, being the best in the world means little. He is outstanding," Pepe told RTP.
"On the field of play, I look at him and I think he is from a different planet. He outdoes himself in every game he plays."
