After a record win against minnows Bermuda put its World Cup campaign back on track, Indian skipper Rahul Dravid cautioned his teammates against any slip-up in their must-win game against Sri Lanka on Friday.

"There are some things which are not in our control, like the net run-rate. The other teams' matches and results are not in our control. What is in our control is to go and try to win the next game and win it as well as possible," Dravid said after India beat Bermuda by 257-runs.

Dravid asked his boys not to sit on their huge win against Bermuda but look ahead for the bigger challenge of overcoming Sri Lanka.

"The real challenge is ahead of us. We had two must-win matches, but have won just one. The guys know what they have to do now," said Dravid, with man of the match and centurion Virender Sehwag sitting in tow.

India now need to put it across Sri Lanka to have a realistic chance of qualifying for the Super 8 stage.

India posted the highest Cup total of 413-5 and then bowled Bermuda out for 156 to record the biggest victory in one-day internationals by run-margin. Dravid underlined the fact that not only his team needed to win but also do it handsomely to up the run-rate.

The Indian skipper saw it as a good sign that dashing opener Virender Sehwag returned to his swashbuckling ways ahead of vital clash against the Sri Lankans.

"Viru (Sehwag) is a very good player and I'm happy he's part of my team -- a key member. He's back into form just when we need him before a very critical match," said Dravid.

Sehwag, without a hundred in the last 61 games, smashed 114 off only 87 balls with 17 fours and three sixes and looked a relieved man.

"The effort he has put in is fantastic. It is nice for him to get runs. All credit to him. To be honest, we expect a lot from him. He has been picked to score more than one hundred for us," said Dravid.

Sehwag said a big innings from him was long overdue and he was just waiting for his chance.

"I had the confidence. I knew the captain, coach and selectors were backing me up and I had to deliver," said the aggressive opener.
