Rooney is not 'world class'. It takes a hell of a lot of technical ability to be world class. There's very, very good, and then there's world class. Zidane, Ronaldo, Messi, C. Ronaldo were/are world class. Rooney suffers from the over-hype of the British media.
Phil Jones will be branded as world class in two years time regardless of how well he develops. He may well prove me and a lot of football fans wrong and become a 'world class' defender but he'll certainly be tagged with it in England before any other country's press.
Rooney under Ferguson hasn't developed the way I thought he would do when he broke through at Everton. Again, I ask you, Rooney couldn't have played that lone striker role like Aguero did today. There are too many flaws in his game still that stops him from deserving the title of 'world class'.
He is clearly world class and is in the tier below Iniesta and Xavi regarding the best players in the world alongside the likes of RVP, Silva, Fabregas etc....
I honestly think you're being generous putting him in the same bracket at van Persie, Silva and Fabregas. You genuinely think that Wayne Rooney is of the same level as those 3 players? Take off the English tinted spectacles. I'd possibly put Gerrard in that bracket, that's it. He could have become one of the greatest ever players if he left Liverpool. He's never developed into a top top level player like Xavi, Iniesta etc.
