Sydney: After Team India’s dismal performance against Australia in the Commonwealth Bank Series here on Sunday, Indian skipper Mahendra Singh Dhoni said that he was unable to pinpoint any particular reason for India’s failure in the ODI tri-series.

"I can't pinpoint one particular reason. To win, we need to bat well. I have lost most of the tosses and that has also led us to situations where we have had to bat second under lights and that has made things difficult for us. We haven't been able to perform to our potential," Dhoni said at the presentation ceremony.

Talking about Sunday's defeat, Dhoni said that he was pleased to restrict Australia for 252 but left too many overs for the Nos 7, 8 and 9. “Overall I was quite happy to restrict Australia for 252 when I thought they could have scored 270 plus. Sehwag really bowled well for us," adding that things got a bit difficult once Irfan got injured.  "Things became difficult as Irfan got injured and Umesh also went for runs although he came back well."

Meanwhile, Australia's stand-in captain Shane Watson said he was nervous on leading the national team for the first time. "It's a nice start. But I was certainly nervous not knowing what to expect but all worked well. When you are not leading you can just stand at the first slip and concentrate on your bowling. But here you have to think and try to make an impact," Watson.

Man-of-the-watch David Warner said, "I obviously needed runs and it was a crucial game. I backed myself and tried to work the ball around. I tried to hit the deliveries on merit. Also running Tendulkar out with a direct hit was special."
