The Aussies are currently leading 2-1 with rain having played spoilsport in the fourth ODI at Ranchi, and it could well be a similar result tomorrow given the bad weather here as well.
If tomorrow's match also gets abandoned, there will be only two ODIs (Nagpur and Bangalore) remaining, which India will be required to win in order to clinch the series.
"We all want the match to happen as we're trailing 1-2. There's not too much pressure as such. If this match doesn't happen, then we have to win the remaining two matches," said Jadeja on the eve of the fifth One-dayer against Australia at the Barabati Stadium.
Although the match is likely to get washed out tomorrow, Jadeja insisted that the hosts were mentally prepared to take the field even if it is not a full 100-over game.

"It doesn't look like there will be a match tomorrow! Maybe if it doesn't rain tonight, we are mentally prepared to play a match, no matter of how many overs it is," he said.
Yuvraj was seen with a bandage and asked if he was alright, Jadeja said: "No, I don't think there's anything serious. Everyone was playing football. I don't think there should be any major injury. Everyone is fit and we all worked hard in the nets.
