Bangalore: Indian coach John Wright warned on Tuesday that the coming tour of South Africa would be "lot tougher" than the Indians had recently against Zimbabwe and Sri Lanka."South Africa" is a very formidable side. It would be a tough series. A lot tougher than the two we just had," Wright told reporters on Tuesday. India drew the series against Zimbabwe and lost to Sri Lanka. He said he does not expect "too many spinning wickets" in South Africa. "We have to go there with a positive and right attitude," Wright stressed. "When we bat, we have to get good runs in the first innings and then bowl and field well. We have to be very positive." India lost the series in Sri Lanka because it played "poor cricket" both with the ball and bat. "We had a young side in some aspect. We fought back in the series but in the last Test we did not play to our potential," Wright said. "You can't expect to win when you make fundamental errors. That's a disappointment. We have to learn from that." Asked what needs to be done, the coach said, "Improvement is needed in running between the wickets, creating runs, rotating the strike and stopping ones."
