The idea that Anderson only performs well under clouds is antiquated. Sure it was a wet summer by Aussie standards but the conditions were not your trademark Anderson skies that people like to use to try and write him off. And Burgey knows this too, he just can't bring himself to admit that Anderson is world-class.
That being said, when he is playing at home I wouldn't swap Anderson for anyone, including Steyn. He's a World XI bowler wherever, but at home he's the best bowler you could have in your team.
Zaheer has a lot of expectation on him in this series and him against Cook should be mega. Can't see him lasting all four Tests and don't think he'll go as well as Anderson.
Will be a good battle though.
