Aaron Finch announced his retirement from ODI cricket last week following his horror run of form, but he will stay on as skipper for the T20 World Cup in Australia, which begins next month.

Marsh has plenty of captaincy experience at Western Australia, but he played a straight bat when asked about the prospect of taking over as ODI skipper.

"I need to be very careful what I say here, you know I don't like headlines," Marsh said with a smile. "I think there may be conversations down the track. But this World Cup is so important to us as a team, and for me personally it's everything I've worked for over the last couple of years.

"Cricket Australia have a bit of time to make that [captaincy] call over the next few months, and we'll see where it lands."

Marsh was full of praise for Finch, who averaged 38.89 during his glittering 146-match ODI career.

"He will be sorely missed in our change rooms over the next few years," Marsh said. "[He scored] 17 one-day international hundreds and I really hope he goes down as one of the greats of Australian cricket when it comes to white-ball cricket. Just a ripping bloke and a great captain."

Marsh is confident his ankle injury will heal in time to allow him to take part in home T20 fixtures against the West Indies, England, and India prior to the World Cup.

"The ankle is coming along pretty well," Marsh said after Western Australia's season launch on Thursday. "It's on the minor end of the [scale] but with the World Cup coming up, it's really the only opportunity to get it right for that.

"I'm certainly not worried about it, it's coming along well and hopefully I'll be right to play against the West Indies in a few weeks' time."
