They were handed out a crushing 41 run defeat by the Australians followed by a sound drubbing at the hands of arch-rivals India.
Arthur said he had chatted to current Proteas coach Ottis Gibson after Sunday's match, and he explained how quickly things could deteriorate for a national team of South Africa's magnitude when results do not go well.
Former head coach and fast bowler Waqar Younis Pakistan weren't anxious about losing Sunday's match against South Africa, giving them the freedom to pay their natural game.
With five points from six games, Pakistan are now at the seventh spot in the points table. They now need to win all of their remaining games to stand a chance of progressing ahead. "We started nicely, got a partnership going, then wickets fall", he said.
"But that challenge we are going to have as a team all the time. It probably is - but we've got to win three games".
Du Plessis said after the heart-breaking loss to Pakistan that he and few others were against some of the top players from participating in the IPL. But the fact is that no batsmen has scored more than 68 in a tournament played on good tracks, which is an indictment on the whole team. Whether that's New Zealand, Afghanistan, Bangladesh.
"What those guys have been through at this World Cup will be invaluable and the process starts with them". We changed the combination in this game. "He's the main factor, the turning point, the way he batted in the last 15 overs, it was like Jos Buttler", Sarfaraz said at the post-match presentation ceremony.
"Our boys hurt, all of us hurt, incredibly".
"But we did try and get him not to go to the IPL; to try and stay and get fresh. I hope the innings will now give his career the deserving lift, more importantly, the recognition".
Chasing 309 to remain in the hunt for a last four berth, South Africa's survival bid petered out on 259-9. Yet, when referred to third umpire Chris Gaffaney, he decided there was inconclusive evidence to overturn the on-field decision that the ball had bounced before the catch was taken - much to the fury of the South Africans. "So when we put three disciplines together, we'll be exceptional", he said.
Waqar further wrote that Pakistan would be closely watching England against Australia on Tuesday, which would be a crucial match, particularly if Australia beat England.
Disciplined Pakistan bowling saw Shadab Khan and Wahab Riaz take three wickets each as South Africa surrendered without a fight.
