"Do we have enough countries winning medals? Maybe what we'll say in wrestling, for example, is that each country can only enter one athlete, or in swimming, you can only enter two athletes.

"That's something we need to work with – that distribution of medals."
Midway though the fourth day of competition on the Gold Coast, Australia had 23 gold medals, England was second on the table with 17, while Canada was a long way back in third on six.
Australia and England have won more gold medals between them than the other 69 nations at the Games put together.
And in team sports, the big guns are handing out massive mismatches.
Australia's netballers beat Northern Ireland 94-26, New Zealand beat debutantes Ghana 12-0 in women's hockey and Australia's women's basketballers thrashed Mozambique 113-53.
The CGF has started a transition from open entry for teams to a stricter selection sport-based criteria and has capped the number of athletes at 4500 for each Games.
Team sports, weightlifting and para events used Commonwealth rankings and selection criteria for the first time at the Gold Coast Games.
Grevemberg says the ultimate aim is to have sport-specific criteria across the board.
"That will drive greater certainty in the overall process and up the credibility and legitimacy of the event," he said.
"But you can only do it one Games at a time. Change is hard sometimes, you don't want to move too fast too soon."
While Australia and England have dominated the early days of the Games, largely through swimming and cycling, Grevemberg sees a shift coming with the athletics starting on Sunday as the African and Caribbean countries come into their own.
