Rooney scored two goals in United’s 4-0 win over AC Milan in the Champions League on Wednesday.
He told Sky Sports: “He is one of the best in the world at the moment, if not the best.
“Wayne will continue to play like that because he is a passionate player, he is a young player, he wants to learn.
“With Messi and Ronaldo he is up there with the best, if not at the top.
“He has always scared defenders, whoever he has played for. He has always been a worry for any defender and any team. Let’s hope he continues that.”
