Indian captain Rahul Dravid said it is going to be a challenge to integrate Twenty20 format in domestic cricket in the country.
"Twenty20 match at international level is always going to be a success. Fifty50 was a success. That's not the challenge. The challenge is to see that it's a success in domestic form of cricket. How it's going to be done. What's the way forward. I think, it's going to be trial and error (method)," Dravid said.
"Twenty20 cricket is ideally suited for England, where it's played in the evening (between 5 pm and 9 pm), because of the nature of the game. It's a brilliant game for England."
He said: "in India one has to learn and experience as one goes along to see how it works in domestic cricket. At this stage, one can't say for sure this is the way it will work. One has to wait for a few years to see how it works and learn from experience."
"In 3-4 years, one might come up with a formula or format (for Twenty20) that would be suitable for sponsors and players," added Dravid at a press conference to announce the second edition of Twenty20 Cricket tournament for Bradman Cup that gets underway.
He said: "spectator interest in Test matches have already seen slight decrease. But I don't think that is a reason for the (decrease) is just because of Fifty50 (one-day game) or Twenty20. There are lot of other factors," Dravid said.
"In terms of players, I don't think so. Test cricket will always be very important for players. I don't think players will ever take Test cricket lightly," he said.
Asked if Twenty20 cricket would "hamper" cricketers who are doing well in Test cricket, he said it's up to the players to adapt to the new version. People had similar concerns when one-day cricket was introduced, but it's debatable whether one-day cricket had positive or negative impact on Test cricketers.
On his impressions of the Twenty20 games, Dravid noted that he played only a couple of games but said "one of the things you do enjoy about Twenty20 cricket is its atmosphere...Great atmosphere!"
