Real Madrid coach Jose Mourinho says Cristiano Ronaldo is proving himself the best player in the world.

Ronaldo proved the matchwinner at Champions League opponents Manchester United this week.

"Cristiano is the best in the world. I saw Maradona a couple times and I've never seen Pelé, but Cristiano is incredible. This man is the best. But even he can't win on his own. The key is in the team," said Mourinho.

"We never say that Cristiano is responsible when we lose a game, and we can't think that he is the only one who wins it. Without the team he isn't anything, but the team without him isn't the same."
