Varun Chakaravarthy's mystery has become history: Kris Srikkanth

Former India skipper Kris Srikkanth slammed KKR spinner Varun Chakaravarthy's bowling in their match against MI on Sunday. "Just bowling googlies all the time will not sustain. He has to get some variations and get the leg-spin going. There is no mystery with him anymore," he said. "Unless Varun learns to spin the ball...he will struggle," he added.
