Former Australia coach Eddie Jones has voiced his concern at suggestions that rugby union rules should be altered to encourage a more attacking game.
Jones guided Australia to the World Cup final in 2003
In the wake of a try-less World Cup final and games decided by penalties, Australian Rugby Union chief executive John O'Neill called for rule changes.
But Jones said: "We've got to be careful we don't change the game just because we want entertainment.
"We'd be very, very foolish to look at changing to make the game like league."
Experimental laws have been introduced in Australia aimed at creating a more appealing game for the spectators.
But Jones, who advised champions South Africa in the recent World Cup tournament, insisted: "There's nothing wrong with the game.
"We've had some fantastic games at the World Cup and we've had some arm wrestles, but when you're playing for a big prize you're sometimes going to play quite simple rugby.
"I don't think there's anything wrong with that. In Europe they don't care about the way rugby's played. If it's fast and free it's good, if it's tight and grinding that's good, and the crowds at the World Cup were enormous."
