Senior off-spinner Harbhajan Singh is of the opinion that India's home series against Sri Lanka served little purpose ahead of the gruelling tour of South Africa. India have already lost the series and are staring at a whitewash against the Proteas. Questions have been raised about Indias preparation for the tour and Harbhajan gave his perspective. Look I believe the last Sri Lanka series at home served little purpose. We hardly gained anything out of it. Rather a few players could have gone to South Africa early. If not Dharamsala could have been a great place for preparation, Harbhajan said. Its high altitude, cooler weather, seam movement along with bounce would have given them ideal preparation before a tough assignment like South Africa.
