A beaming Sourav Ganguly asked his teammates to celebrate the 82-run victory over England but said the next match against Pakistan was "one big game we must win".

"This was the biggest victory for us in the tournament so far. We need to celebrate every win because every win is special," Ganguly said after India's win Wednesday that left the team at the doorsteps of the Super Six stage.

"But we can't be happy with just this. We have got to go further," he said.

The victory gave took India's tally to 16 points, almost assured of a Super Six berth, and Ganguly admitted it would take the pressure off his teammates in the high-voltage game against Pakistan.

"This win has probably given us a great chance to qualify for the Super Six. So the pressure would be less when we take on Pakistan. But then that is one big game which we must win," he said.

Ganguly was all praise for left-arm seamer Ashish Nehra who destroyed the England batting with dream figures of 6 for 26, the third best by an bowler in a World Cup.

"Hats off to him. It was his sheer determination that saw him perform so well," said Ganguly about the bowler who till the morning was not sure of playing because of an ankle sprain.

"All credit to him and physio Andrew Leipus (who got him fit)," Ganguly said.

Nehra, who deservedly won the man of the match award, also credited his speedy recovery to Leipus.

"I played just because of him," he said.

"I just tried to keep a good line and length. The pitch had a bit of bounce on it and it worked," he said, and added that his ankle was feeling better.

England, who had scored a big victory against Pakistan in their previous game, are now left requiring to beat Australia in their last game to remain in contention for a Super Six berth.

"We have to beat Australia at some stage to win this World Cup. So why not on Sunday (March 2)," England skipper Nasser Hussain said.

Hussain said losing the toss was not decisive but admitted that batting second under lights was difficult.

"We had checked the scores here. Five or six times sides chasing had won," Hussain said.

"But yes, today under the lights it did zip around a bit. All credit to the left arm seamers (Nehra and Zaheer Khan). They bowled really well."

Hussain felt letting the Indians post a a total of 250 after keeping the batsmen in check during the middle overs proved costly for his side.

"We should have tied them at 220-230. I was pleased with the way we fought back after Sachin Tendulkar and Virender Sehwag had given them a great start. But they played well at the end. And we lost our focus a bit," he said.

Hussain praised Andrew Flintoff, who returned with outstanding figures of 2-15 before top-scoring for England with 64 runs, for his all-round performance. "He batted well, bowled well and fielded well. He had a very good game."
