"I think the key is going to be the ability to take 20 wickets," Dravid told reporters at Lord's, where he is playing for MCC XI against the Rest of the World in a match marking the ground's bicentenary today.
Under Dravid's leadership, India, in 2007 had won the three-Test series 1-0 -- one of just three Indian Test series victories on English soil.
Dravid pointed out that left-arm pacer Zaheer Khan, who is not a part of the current series because of injury, and retired leg-spinner Anil Kumble played a vital role in the team's victory in 2007.
The touring Indian squad comprises experienced pacer Ishant Sharma -- the only bowler in their squad to have played a Test in England prior to this trip - but he was off-colour during the warm-up games. The pace unit also consists of Bhuvneshwar Kumar, Mohammed Shami and Stuart Binny.

Dravid said unless these bowlers are able to swing the ball, it would be difficult to get the better of the English batsmen.
Dravid, however, is confident that the young batsmen in Cheteshwar Pujara, Shikhar Dhawan and Rohit Sharma would come up with impressive performances.
