Finch remains T20 captain: Smith

Steve Smith has confirmed he has no plans to be Australia's captain in all three forms of the game, saying the Twenty20 leadership is still Aaron Finch's domain.

Smith will lead Australia into action in their T20 international against England in Cardiff on Tuesday morning (AEST), fresh from a 23-run Duckworth-Lewis victory over Ireland in a one-day clash last Thursday in his full captaincy debut.

But despite recently being named both the Test and one-day skipper, the 26-year-old insists he harbours no desire to take control of the Australian team in the game's shortest format as well.

That job, he says, belongs to the injured Finch.

"No, it's Finchy's team actually," Smith said.

"It takes a bit of weight off my shoulders, I guess, in this form of the game.

"Finchy is going to lead this team going forward, (this match is a) one off for me going forward."

Warner prepares for one-off T20 in Cardiff

Finch, who was announced as the T20 skipper in August last year, is sidelined with a broken foot he suffered playing for English county side Yorkshire this winter. The injury came on the back of a serious hamstring problem he suffered playing for Mumbai Indians in the Indian Premier League.

The 28-year-old is expected to hold the reins as Australia attempt to break their T20 World Cup duck in India next March.

Whether the role of deputy will fall to Smith or his vice-captain at Test and ODI level, David Warner, is another decision which has not been clarified just yet.

"I don't know ... I'm not sure if they've actually appointed a vice-captain for that," Smith said.

"So (it's a) one off here in Cardiff (and) hopefully we can get another win."
