Now where did I say no to that? That's why I say you imagine things, or you hallucinate. Now carefully read this word by word once more, without blabbering non sense.
You keep referring to some point about Murali doing well against Australia and India at home as if he is a good player of spin where Warne didn't do well against Sri Lanka and India at home and did well against the rest as if there is a class difference. No, the bigger difference is that Warne was bowling on pitches that were, bar Sydney, unsuited for Spin.
Vettori, and few Pakistani spinners have done well in SL. Only good spinners gets spared here. SL were good players of spin (but not now IMO), and that is accepted. And same has happened in Australia as well. Virtually no touring spinner has got on top of Aussies.
Better spinners than Vettori have failed there and it's a point you've brought up yourself plenty of times: spinners get smashes, usually, in Sri Lanka. The difference between the spinners in Australia and Sri Lanka is not only do they face poor conditions, but batsmen that will rip you apart. In Sri Lanka, at least the conditions are conducive for spinning.
You are conviniently forgetting that we can have and idea about performance of players by looking at averages. And when this adjustment is made it shows Warne and Murali both have performed up to same level at home. Even after this correction is made Warne's stats against SL and IND is poor. If the same pattern to be expected, then you shuould see Murali averaging about 61 against India in SL, vs Warne's 65 in Aus, and it's not the case, because the average difference is 4 runs between spinners in Aus and SL during their times. Now how much you try to twist, Warne has done badly against India, even after considering the pitches are unresponsive.
No one is denying the fact that Warne did badly, even in Australia, because he also did so in India. The point is, Murali did not face India in Australia, and Warne did not face India in Sri Lanka; so your bigger point is lost. Especially considering Murali does pretty badly in Australia and Warne does better than Murali in Sri Lanka.
Also, for your stats here have left in B/Z in Sri Lanka. The Sri Lankan average rises from 31.4 to
34.4 and the Australian average goes from 35.4 to
36.1 increasing the difference by more. Murali becomes 12.2 points superior to other spinners and Warne 9.7 points superior.
I am pretty sure that's not accurate either as it takes into account home spin bowlers as well as visiting ones.
