The former Australia skipper, who turns 38 next month, has failed in three innings against the Proteas during draws in Brisbane and Adelaide and pressure is building on the 167-Test veteran ahead of Friday’s third Test in Perth.
Ponting admitted in Adelaide that he was a realist and knew that if he did not start scoring runs then he “definitely” would not be in England for the Ashes in July and August next year.
Arthur, who is also on the selection panel, told reporters that Ponting’s future had not been discussed by selectors.
“We unanimously back Ricky Ponting to get us some runs. By his own admission, Perth is a big test for him, but Ricky has prepared brilliantly, he’s really given us everything we could probably have asked,” Arthur said.
“He’ll leave no stone unturned in his preparation for Perth and I’m backing him for a big score in Perth, no doubt about that.
“Inside the dressing room and privately we’ve all backed Ricky Ponting,” he added.
