Jacques Kallis

South Africa's greatest all-rounder Jacques Kallis has figured out why his country's batsmen are struggling against Indian wrist-spinners Yuzvendra Chahal and Kuldeep Yadav -- the Proteas are not facing bowlers like those in the domestic circuit at all. India have taken an unassailable 4-1 lead in the six-match series with Chahal (14) and Yadav (16) accounting for 30 wickets between them. "It takes time to read good leg-break bowlers. We have to accept we don't have enough world class leg-spinners in our country. So, this is a learning curve for the youngsters in our team," Kallis told PTI in an interview.
