Manchester United ace Wayne Rooney admits he was impressed by Ronaldinho in their victory at AC Milan last week.

Ronie scored one and created the other for Milan in their 3-2 defeat to United.

Rooney admitted: "He is a world-class player.

"I hope he doesn't go to the World Cup with Brazil ­because he's unbelievable.

"He's so strong and quick still. He can do amazing things with the ball."
