Former England cricket captain Mike Atherton has called on the game's most powerful countries to do more to help the weaker nations, including New Zealand.
Atherton, a tough-minded skipper and a forthright commentator on the game, said the widening gap between the haves - India, England, South Africa and Australia - and the have nots was a major issue for the sport.
Speaking during a panel discussion in Brisbane on the eve of the first Ashes test, Atherton said a more even distribution of the games' profits was essential.
"If you only have three or four strong nations, cricket is diminishing all the time and you get what's happening at the moment, with England playing Australia more often and playing India more often, and that fixture list diminishes," Atherton said.
"You can't call it the world game if only four nations play the game ... It's in the long-term interests to make sure the other countries are strong. I think strategically it's the biggest issue that faces the game, really."
