waqar younis for swing bowling and shane warne is the single best bowler ever closely folowed by murrilatharan
I will vote for Muralidharan and shane warne both are amazing bowlers. You cannot compare both of them both are great
I will say Muralidharan and Allan Donald are the worlds best bowler with there unique bowling pattern.Muralidharan's "Dusara" is just fantastic.
I think ishant sharma is the best bowler. At the time of starting his odi career he performed a lot but he now he is not so.
