Durban:Buchanan wants Australian selectors to request Shane Warne to lead Australia in the upcoming T20 world cup in Australia.
Buchanan was much impressed by the performance of Warne and Gilchrist in the ongoing IPL tournament.
Former Australia's world cup winning coach was against risking top Test players with Ashes approaching and suggested either Warne or Gilchrist captained the side.
He said Warne, Gilchrist and Matthew Hayden should have been considered, along with specialists such as David Warner, Shane Harwood, Cameron White, Shaun Tait and Moises Henriques.
"Selectors should have been talking with former players to make themselves available for this particular event. I would be looking at Warne or Gilchrist as captain," he was quoted as saying by 'The Age'.
"If I was a selector I would not be risking, wherever possible, key Ashes players such as (Ricky) Ponting, (Michael) Clarke, (Mike) Hussey, Hughes, (Brad) Haddin, (Shane) Watson, (Stuart) Clark, (Simon) Katich, (Peter) Siddle, (Mitchell) Johnson."
