Alastair Cook should continue as England's one-day captain beyond this series - if that's what he wants, says Sir Ian Botham.
Cook, 29, insisted that he is "desperate" to remain as skipper before the fourth one-day international against Australia, which the tourists won by 57 runs to avoid a 10th-straight defeat.
On Sunday Cook suggested that he might step down from the limited-overs role as England, trounced 5-0 under his leadership in the Ashes, let the one-day series slip through their grasp.
But Botham said he still believes the opener is still the right man for the job if he wants the responsibility and is prepared to make the team his own.
"It was nice to see Alastair Cook smiling; he's had a tough, tough winter," said the former all-rounder following England's success in Perth.
"Personally, I don't have a problem with Alastair Cook doing the captaincy if he wants it.
"I don't really see who else is going to do it, to be quite honest, at this moment in time so let him go. If he doesn't want it then you re-think.
"Cook and [head coach] Andy Flower have got some work to do. They've got to sit down and discuss where they want to go. Alastair Cook has got to stamp his authority on the Test side and the one-day side if he stays in charge.
"The 'House of Andrew Strauss' has been blown away. Now it's a chance for Alastair Cook to build his house and show everyone how he is going to do it. He's got to stand up and do that."
England claimed their first international win of the tour after posting 316-8 off 50 overs thanks to Ian Bell's 55 off 52 balls, an impressive 70 from Ben Stokes and Jos Buttler's late fireworks, which yielded 71 off 43 balls.
All-rounder Stokes then claimed 4-39 as Australia were bowled out for 259 in 47.4 overs, wicketkeeper Buttler pouching five catches, safely holding onto a skied edge from James Pattinson to finish the match.
Botham said that both Buttler, 23, and Stokes, 22, have key roles to play in improving England's fortunes.
"England have been well off the mark but today they hit their straps, they played well, in particular two of the younger players - Buttler and Stokes - so well done to those two guys.
"Test cricket could well be around the corner for Buttler. He's not doing himself any harm - and I think that's the whole point of where England are now. They are going through this rebuilding process. They are building for the World Cup, which is a little way down the line, but you need to give yourself time.
"I think Buttler and Stokes will definitely have a big part to play. Chris Jordan has done well, as has Morgan so they've probably got the backbone of the side now and they will play around with it."
Man-of-the-match Stokes, who scored 120 at Perth in only his second Test in December, said England are gaining vital experience in Australian conditions ahead of next year's 50-over World Cup.
Botham said that the Durham all-rounder is proving that he not only has the ability, but the attitude to be a consistent performer at the top level.
"Stokes has got a bit of devil in him; he's got a little bit of arrogance, which I think is essential; he's prepared to mix it with the opposition.
"When he walked out here in the Test match in Perth and got that magnificent hundred, Mitchell Johnson and the guys were all trying to get into him but he gave it back and batted magnificently.
"He obviously likes batting on this ground and I know why, because the ball comes through and it's easier to hit through the line of the ball. If you are a bowler and you bowl well you get rewards because the wind can help you and it tends to swing.
"Stokes has continued from where he's left off in the Test series. He's been the real find of the tour - the only find of the tour probably!"
