The Manchester United ace has scored an amazing 27 goals for the Red Devils this season while Ronaldo has scored 18 goals for Real.
Queiroz said: “Rooney is doing very well; I worked with him for many years at United. He is a fantastic player and a great professional who is getting better all the time, but Cristiano is the best player in the world.”
The Portugal coach added: “I hope that he will come through the World Cup having scored lots of goals and still the best player in the world. If he does that, then he can help Portugal to big success in South Africa.”
