Jacques Kallis has urged South Africa to learn from England’s remarkable revival in ODIs following the team's early exit from the World Cup recently.
A 49-run defeat by Pakistan at Lord's ensured that there is no way South Africa can make it to the top four in the World Cup.
Faf du Plessis admitted South Africa's World Cup exit was embarrassing as he termed his under-performing side ‘mediocre’ and urged them to take responsibility for the disastrous show.
But Kallis said South Africa should draw inspiration from the way England recovered after suffering a woeful first-round exit at the World Cup four years back.
Eoin Morgan's side currently sit at the top of the ODI rankings and are touted as favorites to lift the trophy this year.
"England used the disappointment of their performances in 2015 to rebuild their team and totally change their mentality and approach to one-day cricket," wrote Kallis in an International Cricket Council column.
"England now play without fear and aren't afraid to make mistakes. For me, South Africa have approached things too defensively at this tournament and they need to attack each match with much more positivity going forward."
Kallis said altering their approach did not mean the Proteas had to make dramatic changes to their squad.
"You don't need to make wholesale changes, England are still captained by Eoin Morgan, as they were four years ago," he said.
"A total clean-out is just not the way ahead. We need to be more considered and thoughtful.
"South Africa have some great young players in their 20s (Kagiso Rabada, 24, Lungi Ngidi, 23, Andile Phehlukwayo,23, and Aiden Markram, 24) and they can be the foundation for the future."
Kallis added: "The first thing that needs to be looked at is the brand of cricket South Africa are playing.
"England are proof how quickly things can change in four years, so long as you have the right approach."
