I rate Kumble better than Warne. out of 10 Kumble gets 8 and warne 7.9 . Reason being warne always had Mcgrath and company for support. Kumble didnot have any. during the last 17 years Australia have won so many matches and so warne got chance to bowl in 2 innings of every match. As far as india is concerned ,w e have won hardly so naturally kumble got less chance to bowl than warne and too not so friendly conditions as his partners were no where near him
