Aaron Finch at centre of brutal Aussie selection call at T20 World Cup

You can’t talk yourself into form.

Aaron Finch knows that better than anyone because he's been trying to convince himself he still has what it takes to compete at the highest level.

The truth is, his best form is so far in the rear-view mirror it's not funny and it looks like having fatal consequences for Australia's T20 World Cup defence.

The Aussies have one foot out the door after a humiliating first-up 89-run loss to New Zealand in Sydney, needing to win all six remaining games and repair a punctured run rate in the process.

Finch's last seven T20 innings read: 7, 58, 15, 12, 13, 0, 13.

He looks fatigued, lost for answers and down on confidence – and when your skipper's off his game the negativity often seeps into the rest of the team.

There was nothing to hang onto from this SCG performance, nothing to convince you this was just an aberration and things will come good.

The bowlers were 'pongo-ed', the tactics questionable and the batting fell apart like a cheap pie as Australia chased an improbable 201.

Finch made just 13 and no longer demands a spot in the Australian top order.

Should Aaron Finch make way for Cameron Green?

Replacing your captain one game into a tournament, especially a home tournament, is a big call but Cameron Green should be in the side and opening the batting.

The West Australian has reached the 70s four times in his last nine T20 innings and adds an extra dimension to an Australian bowling attack that could do with some variety.

There are also calls for Steve Smith to come into the side as a 'floating' batsman, capable of capitalising on a good start or Spak-filling an innings if early wickets are lost.

But judging by the chatter, not much is going to change heading into Tuesday night's must-win encounter against Sri Lanka in Perth.

"You can’t go into your shell in T20 cricket. You have to be able to transfer pressure back onto the opposition as quick as you can," Finch insisted after the New Zealand debacle.

"At times that comes with risk. You have to be prepared to wear the consequences of taking risks.

"We haven't gotten it totally right with bat or ball – we've got to look at ourselves in that regard - but I'm still committed to playing the same way that won us the last World Cup.

"We still feel as though we have the right structure of team and the right players to win the World Cup."

We will see. The time for talk is over.
