"We're playing a strong team in India, and as a team, we know we're not good enough at the moment and we have to turn it around."
South Africa need a new strategy after an abysmal start to the World Cup because 'Plan A' has already been ruined by injuries to their pace attack, captain Faf Du Plessis has said.
Veteran quick Dale Steyn missed the first two matches with a shoulder injury and South Africa were duly thumped by hosts England in their tournament opener before losing to unfancied Bangladesh at the Oval on Sunday.
They suffered another serious setback against Bangladesh when pace bowler Lungi Ngidi went off with a hamstring injury early on and Du Plessis said South Africa would only cope if they changed tactics in their remaining games.
"I'm extremely disappointed," the 34-year-old told reporters.
"Our plan in both the England game and (the Bangladesh) game was to try and make sure we target them with aggressive bowling.
"Plan A is gone because Plan A was those main bowlers playing together and they haven't played a game together on this tour.
"Initially, Plan B was Anrich Nortje as an extra pace bowler that we had lined up for if we had an injury, to have another X-factor bowler that can bowl 145kmh-plus. He got injured, as well.
"If Anrich was here, you could say, 'listen Dale, it's getting to that time now where you need to play or we need to substitute you.' But now we have got two or three down."
"So now we have to really look at what we can do to try to be effective -- is it playing all-rounders together, do we play two spinners? Now it's reshuffling all our cards to see how best we can deal with it."
Steyn is expected to be fit for Wednesday's game against India and Du Plessis said every member of the squad needed to start living up to their potential.
"I have to believe that we can still win the World Cup," he added.
"I won't be South African if I said no.
"Every single player in our dressing room is not playing to their full potential and that's why we're not putting the performances in. As soon as that starts happening, then those things will change.
"We're playing a strong team in India, and as a team, we know we're not good enough at the moment and we have to turn it around."
