Murali will easily get to 500 before Warne. First no one knows if Warne will even be playing, what if he plays terribly in the lead up to the tests, i doubt he will get picked. Then the fact Murali seemingly bowls almost half of Sri Lanka's overs, the reason why he takes so many wickets per matches. I hope neither gets to 500 and neither breaks Walsh's record, as I have a huge dislike for both Murali and Warne.
