The former Aussie skipper, who led his side into four Ashes battles, insists England are wasting valuable time prevaricating over whether Alastair Cook will quit.
And he believes that if the current Test skipper is having any doubts about whether he will lead England at The Gabba in November, he should step aside now.
“Knowing the enormity of the series and the pressures that come with being in charge being thrown in on the eve of the Ashes would be a big ask,” said Ponting who is working as BT Sport pundit at the Big Bash.
“For Joe’s sake and for English cricket’s sake if England cricket is going to make the decision that Alastair is not going to captain in November December they are better off making that decision sooner rather than later.”
Alastair Cook is yet to decide whether he will continue as England captain
Root, who is currently in India as England wrap up their tour with three final T20 internationals, is expected to find out whether he is to succeed Cook at the end of the month.
Aussie legend Ponting believes Kevin Pietersen’s Melbourne Stars outfit may just find Perth Scorchers too hot to handle on their home patch in the first of the Big Bash two semi-finals.
And he is also predicting that Brisbane Heat will complete a white-hot line up in the final with victory over Sydney Sixers on Wednesday morning.
“The competition this year has been the most even of any year,” he said. “And to try and pick a winner this season has been near on impossible.

England headed to Sydney with the 2010-11 Ashes in the bag but a series win was at stake. Hundreds from Alastair Cook, Ian Bell and Matt Prior set up a total of 644 before the seamers forced the tourists to an innings win
“But the Stars have been pretty depleted on their squad from the start for the season with injuries and international call-ups and they’ve found it a little bit difficult last couple of games.
“I understand Marcus Stoinis will be released for them which is a good inclusion for them but Perth are a strong side and I would expect they would win the home semi final.
Brisbane have got through on the back of a few heroics from a few players. Brendon McCullum, Chris Lynn and Mitchell Swepson their leg spinner has done really well.
“The Sixers just seem to get the job done. Their bowlers have done well but only two of their batsmen have made over a 100 runs in the tournament but they keep finding the guy who stands up and wins the crucial moment at the right time.
“But I am going for the Scorchers to beat the Stars and the Heat to beat Sixers.
“And if those two teams make the final it will be in Perth and I think can win. Balance of their squad looks right and I can understand why they have been the most successful team across the six seasons.”
