South Africa coach Corrie van Zyl admits the aggressive innings from India opener Virender Sehwag derailed his side's game plans on the second day of the final Test.
The Proteas, requiring just a draw in Kolkata to triumph in the two-match series, delivered a middling 296 all out in their first innings and soon saw India surpass that score as Sehwag and Sachin Tendulkar both claimed centuries, with the home side closing the day on 342 for five.
Sehwag secured a particularly convincing knock of 165 from 174 balls, and Van Zyl confessed the attack threw his side off course.
"I think it is unsettling to everybody," said Van Zyl. "The fact that he scores very quickly and gets the crowd behind him. All of that is unsettling.
"That is the time when you have got to stick to game plans and get back to basics.
"I thought, sometimes, we didn't do that and that is the strength of Sehwag."
The tourists can draw some consolation from the fact both Sehwag and Tendulkar were dismissed before stumps, while paceman Dale Steyn also disposed of Subramaniam Badrinath.
"Going into the dressing room tonight I think we are happy with those three wickets that we took," added Van Zyl.
"That just brought the balance of the game back. We need to look at a few things and we need to set up in a few areas."
