Australian captain Steve Smith, like the rest of the country, has simply had enough of his side's middle order collapses.

The Aussies suffered yet another collapse overnight, going down to India in the second ODI at Eden Garden by 50 runs, after losing the final six wickets for 64 wickets.

Smith admitted post-match the Aussies have a worrying habit of collapsing in all three formats of the game and said it must cease.

“We’ve had a lot of collapses and we need to stop,” Smith said.

“It’s a hard one to put my finger on but whatever it is, it needs to change.

“We need to make better decisions when we’re under pressure and start playing the game properly. It’s not good enough.”

Smith (59) and Travis Head (39) combined for a 76-run partnership, but from there Australia lost 8-112 to eventually be bowled out for 202.

Glenn Maxwell (14) and Marcus Soinis (62 not out) were the only batsman in the bottom seven to reach double figures.

“Watching the ball closer or maybe the guys are trying to watch it too closely and forgetting about just playing the game," Smith added, trying to explain the reason behind the trend of collapses.

“250 – we should be getting that on this wicket.

“One of our top four has got to go on and make a big score and ‘Heady’ and I were the two that got in and we weren’t able to do so, so a lot of the blame falls on us.

“It was upon one of us to go on and make a big score and be there at the end. We put on 70-odd maybe – if you turn that 70 into 140 then the game’s closed."

The third ODI of the series is in Indore on Sunday.
