That includes an agonising semi-final loss to New Zealand four years ago — when Johannesburg-born Grant Elliott hit a winning six for the Black Caps off fast bowler Dale Steyn.
But this time a South Africa side without retired stars Jacques Kallis, AB de Villiers and Graeme Smith, have gone under the radar.
“Whether we come into this tournament as favourites or as underdogs, you still have to go out on the park and play cricket and perform to win a World Cup,” Du Plessis told reporters at the Oval on Wednesday.
“Learning from myself that I can speak of in the past, you perhaps feel like you have to do more. You know, you have to be a Superman on the day. You’re trying to win a World Cup. For me, that’s not what we need to do.
“We are a good cricket team. Our results has proven that. We need to stay present in the fact that what we have got on our team is good enough to beat any team on the day and trust that, not go away thinking ‘today I need to be the man that scores 180 off 60 balls’ because that doesn’t give us results.
“If we can be just nice and calm and positive — and even if we make mistakes, to make sure that we completely forget about that mistake and come back into the present and focus on what’s ahead.”
“No longer desperate”
Du Plessis, who has become a father since the last World Cup, added: “Cricket is a very important aspect of all of our lives, but it’s not everything — there’s a lot more bigger things than winning and losing games of cricket.
“And that, perhaps, has changed for me. The fact that I’m no longer desperate. I want to win cricket games but I don’t need to win them.”
South Africa will be without Steyn for Thursday’s match after the veteran quick was ruled out with a shoulder injury sustained playing in the Indian Premier League.
“It’s a big loss to our team,” said Du Plessis. “We did expect it when we picked the squad, Dale was about 60 percent when the squad was picked so it was anticipated. A fit Dale Steyn makes our bowling attack a very strong one.
“Steyn, (Kagiso) Rabada and (Lungi) Ngidi are a real threat in English conditions, that’s plan A in the World Cup. So now it’s just a reshuffle, looking to plan B and C.”
