I congratulate Muralidharan's sucess in getting his 600th test wicket. Under normal circumstances he would have crossed the 700 th test wicket.
He should have been the top man in wicket taking but unnecessarily he was framed for his Doosra and deliberately brought him down just to lift Shawn Warney to the top position which the world knows.
Had a British bowler be in Muralidharan's place such actions would not have taken place at all, even if the Asian countries protested against, under such sircumstances.
I personally consider Muralidharan as WORLD NO:1 and Shawn Warney as World No 2 in the cricket world in the wicket taking record.
