Spinner Stuart MacGill's sudden announcement this week that he would play no more Tests has prompted widespread speculation in Australia that Warne could again don the baggy green cap to terrorise the old enemy.
Warne, who retired from international cricket in January 2007 with a then world record 708 Test wickets, raised the prospect himself last month when he said he would consider an Ashes return if MacGill was injured.
But his manager James Erskine on Tuesday said the 38-year-old was happily retired.
"Warnie's position is he's not going back, he's not playing Test cricket again," Erskine told Australian Associated Press.
"He went out on a fairytale and him coming back would be advantageous to no one. He's got no plans to play Test cricket."
Erskine said Warne had a full calendar and had no time to pursue a Test return.
"This year alone he has commitments on 198 days," the manager said.
