Sri Lanka v Australia - 4th ODI

Despite the pressure from outside noise, the Australian T20 side is set to be unchanged heading into Tuesday's World Cup fixture against Sri Lanka over in Perth, which looms as a must-win clash.

Mitch Marsh fronted the media in a press conference expressing his confidence in the same XI, entrusting his teammates to overcome the first-game hiccup against arch-rivals New Zealand.

"If you look down at our team, we've got a pretty incredible batting line up for a T20 side," Marsh said.

"We're early on in the tournament and things may change but for now I think we've got a really set eleven and one that I truly believe in."

Former Test Captain Ricky Ponting put his selectors cap on urging those at CA in the current role to select all-rounder Cameron Green, with a like-for-like replacement needing to be cut.

Marsh responded in kind to a question posed on the potential inclusion of Green, stating the emerging talent adds great selection pressure to the squad.

"Yes, because he's an unbelievable talent," Marsh added.

"No, because it probably means he takes my spot. So we've had words about that.

"I just told him to calm down a bit and give me another few weeks, and then it is all his.

"But look, I think any time you've got someone like him on the sidelines, it's good.

"It creates pressure within the group. But for now, I think we've got the right eleven."

Marsh will resume his duties, if retained, having been given the green light to return to the bowling crease after suffering from ankle soreness in the tournament's lead in matches.
