David Warner's 'ball-roughing' claims have made South Africa more determined to win the deciding Test, according to their coach.
The Australian batsman accused home wicket-keeper AB de Villiers of deliberately coarsening one side of the ball to aid reverse swing during the second Test in Port Elizabeth.
South Africa won the game by 231 runs to square the three-Test series at 1-1 heading to Newlands this weekend, and their manager Mohammed Moosagee later dismissed Warner's comments as "sour grapes".
But the claim has not gone unnoticed within the team camp, and coach Russell Domingo has warned his players now have an extra reason to go on and win the series.
"It's disappointing when guys throw these accusations around," he said. "It's added an extra 10% motivation to the guys following the comments he has made.
"We pride ourselves on playing the game as hard as we can, but also in a fair manner. I just don't think it is a nice comment to make, I don't think teams
should be accusing other sides of that."
Warner said in the wake of Sunday's defeat: "We were actually questioning whether or not AB de Villiers would get the ball in his hand and, with his glove, wipe the rough side every ball. That's another thing we have to try to bring up with the umpires."
He later posted a message on his Twitter account praising South Africa's performance in the second Test, and Moosagee has said the hosts will not press for any punishment.
