Dhoni did not feel the job was done yet despite his team enjoying a 2-0 lead and said he expects the same level of commitment from all the members of the team in the remaining three matches.

"It was tough and we did not have such a game for a long time. We have to be careful as such wins often make us relaxed a bit. We should remember that the series is yet to be won. We want to win the series and for that each of us have to give 100 per cent," Dhoni said after his side's 15-run victory in Colombo on Sunday.

Although India is just a win away from pocketing the series, he said his team would have to make improvements in some departments of the game in the coming matches.

"Today's game was a tough one during which we have committed some mistakes which we would like to rectify before going for the next match," he said.

"We had couple of run outs. Besides, the bowlers should maintain line and length in the slog overs," he added.

An unflappable Dhoni also admitted that he lost his cool when he found his bowlers clueless during the power plays in the middle of the Sri Lankan innings.

"I lost my cool especially when bowlers got confused with the power plays. I was not myself especially in the second power play," he said.

Sri Lankan skipper Mahela Jayawardene conceded that India played better cricket and were the deserving winners.

"They (Indians) played better cricket today. It was a good game. They deserve to win. We have also some positives to take. We fought back well. It was a bit too much for Kandamby to finish the match. Myself and Kapugedera should have been there," he said.
