Ricky Ponting believes India will face a similar dilemma to Australia if their star players retire at the same time.

Adam Gilchrist is the latest Australian to retire from international cricket, while India may lose Sachin Tendulkar, Rahul Dravid and Sourav Ganguly soon.
"They're the number two team but will lose some top guys maybe before we next play them," said the Australian skipper after his team's 2-1 series win.
"It will be really interesting to see how they get back up from that."
Ponting is confident his own team have survived the loss of Shane Warne, Glenn McGrath, Justin Langer, Damien Martyn and now Gilchrist in the last year.
"I don't know how far we are in front but you would think, given what we have done over a fair period of time, that we would be a fair way in front of the next team," the skipper said.
"It comes down to big moments in Test matches and Test series. This summer we have won most of those big moments."
Australia consolidated their dominance in the Test Championship with convincing recent victories over the teams nearest to them.
At home, they beat Sri Lanka 2-0 in a two-match series, and then India in a four-match campaign.
After some one-day action against India and Sri Lanka, Ponting's team travel to the West Indies for their next Test assignment in May.
The only team that has won and challenged Australia in Australia is India
"Sri Lanka and India are two of the best Test teams in the world and we have just beaten them both here," he said.
"The cricket we have played has been very good and I couldn't be much happier."
While Dravid and Ganguly are 35 and Tendulkar is 34, Anil Kumble, appointed captain last year, is the oldest player in the team at 37.
He preferred to talk more about his team's achievements on the tour, however.
"It goes to show that in the last five years the only team that has won and challenged Australia in Australia is India.
"We had our moments," he said. "It was pretty close in Sydney (where Australia won a tense encounter) and if we had held on for the last seven or eight minutes there it could definitely have been different."
