"It's a pretty inexperienced squad (Australia national team)...There's not many senior players...We lost Mike Hussey and Ricky Ponting. You don't really have the core group of senior players who can knock things on the head.
"Young players are getting a lot of money and getting there pretty easily aren't they? They're getting to the top without having to do a whole lot of hard work, so maybe they're getting ahead of themselves," said Waugh.
Waugh although said Warner's outburst was "no big deal", he insisted that the explosive batsman showed "signs of a bit of immaturity".
"Dave Warner has only played 19 Tests... He shouldn't even worry about these sorts of things. He should just be concentrating on his cricket," Waugh told SEN radio.
