The Pacific's most successful footballer was in Auckland for the official launch of next year's Oceania Champions Club league qualifier.
The competition will be played on a home and away format with six teams - two from New Zealand and four from the Pacific region taking part.
The New Caledonian born Christian Karembeu, whose achievements include 53 caps for France and who won the World Cup in 1998, says the home and away format may be stressful for some players.
But he says it's up to the management to ease those pressures.
"They need to care about their players and to tell them maybe there is a route and limit them where to go and to be competitive for this game."
