The blonde leg-spinner, Test cricket's leading wicket taker, is still an integral part of the team, but at the age of 37 appears to have missed the chance to captain his country.

"It is one of my greatest disappointments as a cricket person and former Australia captain that Warnie has never had the chance to lead the team," Chappell told Reuters.

"The first time I saw him captain was for Victoria in a Super 8 competition a few years ago. He just made it so bloody exciting. Rather than think 'how can I save runs here?' it was put in a catching fielder and give the ball to the best bowler and let's see if we can get another wicket."

Chappell, 63, said he immediately rang his close friend Richie Benaud, another former Australia captain, to tell him about the potential for another great leg-spinning captain.

"That's how exciting he made it for me. To me that's the sad part, I think the public would have loved him to have captained the side." Chappell thinks it does rankle with Warne that he never had the chance to lead his country despite the experience gained from playing 140 Tests, though he appreciates it would have been a brave move to appoint the controversial spinner.

"I think it probably does, he's a competitive person," Chappell said. "Having said that I understand that it would have been a pretty gutsy decision by the board to appoint him.

Chappell believes Warne could keep playing Test cricket for a few more years, though he has doubts about whether he can retain the necessary motivation. Warne has been critical of Australia coach John Buchanan over matters including last month's boot camp, which he was forced to attend.

"Warne is a very old time common sense cricketer," Chappell said. "He bowls a lot. That's what he was saying about the boot camp: 'I don't need to be pushing cars up hills, I need to bowl.' "To play at your best you've got to love what you're doing and if a little bit of love for the game is killed off then suddenly it goes."
