India still trail South Africa by 98 runs with eight wickets in hand but they need to bat out of their skins against a fiery South African pace battery on the final day to save the match.
"The mood in the dressing room is just normal. Our batsmen know what their roles are and who the South African bowlers are. They have studied them and played against them. So we need to dig deep and fight the day out," Penney said last night after South Africa reduced India to 68 for two on the fourth day.
India lost one more wicket yesterday than they would have wanted when Shikhar Dhawan was out caught by Faff du Plessis, with the fielder pulling off a stunning catch at short mid-wicket.
"At this particular stage, he wasn't very happy because the light was poor and they could have come off at any stage. I think he was pretty disappointed," said the coach, describing Dhawan's mood.
Earlier in the day, Jacques Kallis stroked his way to his 45th Test hundred in his last match to put South Africa in a dominating position.
