Captain Finch confident that his superstar batting duo have rediscovered their magic touch ahead of World Cup opener.

You don't lose greatness, and as far as Australia's captain Aaron Finch is concerned, they don't come much greater than Steve Smith.Smith and former vice-captain David Warner will finally make their official returns to the Australian team on Saturday night against Afghanistan, more than 14 months since the ball-tampering incident.

So much has been made about how they will come back from their bans, with the reaction of the crowd and fitting into the Australian set-up again being the chief talking points.

But arguably more important is whether they can score their usual kind of match-winning runs Australia are going to rely on to defend their World Cup.

In so many ways, Smith and Warner look like they are ready to answer that question in the affirmative.

Warner was the leading run-scorer in this year's Indian Premier League, his 692 runs at 69.2 showing clear signs of his best.

Smith warmed to the task a little slower, but enters the tournament with an average of 131.33 across Australia's six warm-up games.

"I think when you are world-class players you adapt again and get up to speed," Finch said.

"(Playing) the IPL was really important. That's a high standard of cricket so it just gets you up to as close as international competition as you can.

"Steve is one of the all-time greats, by the time he finishes the game. There's no question about his batting ability.

"When you're great, you get the game quicker. Things just happen quicker. So there was never any issue about how he would bounce back."

Finch said he even expected Smith's game to benefit without the captaincy on his return, allowing him to spend even more time training.

Smith did exactly that on Friday, spending more time than any other teammate in the nets at Australia's optional session in Bristol.
