None of them are test calibre spinners though all of them proved their mettle in Indian soil for one dayers/IPL etc. Test is a different temperament, particularly for away matches and it needs experience, skills and ability to spin the ball even if the pitch is not in favour. India had very good spinners in Trio, Bedi, Prasanna, Venkat and later followed by cricketers like Doshi, Hirwani, Maninder Singh. The present situation is a culmination of the dominance of One Daysrs and IPL. We may have to wait for couple of years to see good spinners who can win the Tests.
