"Week one was a bad start to the tournament but that's done now," Du Plessis told reporters on Friday.

I truly believe that if we carry those ghosts of the last week with us it's going to be tough to get out of the hole. <p></p> <p></p>"But the conversations in the last couple of days, especially with all the rain around, has given me more time to make sure that the guys are on the right path." <p></p> <p></p>South Africa have the perfect opportunity to kick-start their campaign as Afghanistan have lost their first three games and are the only side below them in the table. "We've got to win the five games and that clarity is what we're trying to achieve," Du Plessis said. <p></p> <p></p>"There was a bit of space for us to make a mistake here or there before, but now everyone has written the team off our backs are against the wall. Hopefully, that allows the guys to play the way that we can, and I truly believe that if we do that we'll be a very dangerous team."

We're in a position now where we need to win five games out of five, so you want your best available for selection," Du Plessis said. <p></p> <p></p>"But if he's not 100 percent, or even 90 percent, in a shortened game with a bit of rain around is it worth the risk?"
