Speaking to reporters at the end of the preparatory camp ahead of Test series against Lanka, he said ''it is not easy to play two games in two days and it will be quite tough and demanding on all the players.'' The skipper was commenting on back-to-back matches which had been programmed in the Asia Cup Tournament, underway in Pakistan.
To a question, Kumble agreed that upcoming batsmen Rohit Sharma and Gautam Gambhir have the mettle to make it to the Test team. ''It was nice to have such good talent waiting in the wings to enter the Test team,'' he said.
''We as a Test team have played exceptionally well during the last two tours. We will sit in Mumbai on July eight to figure out what sort of combination we need for Sri Lanka,'' he said.
About the Sri Lankan tour, he said the players would first assemble in Chennai and after selection, players would take part in a two-day practice session, before leaving for Colombo.
India plays three Tests and five one-day games, with the first Test beginning on July 23.
Kumble said the players were lucky as rain did not hamper the camp. ''It is raining elsewhere in the country and not much cricket is happening due to this. We were lucky with the weather. There was no particular focus. We had a few hits, trained and used some dip instruments in the gym,'' he said.
He said the camp helped players as they could play as a group and it was done in a relaxed manner.
On absentees Sachin, Sourav: Veterans Sachin Tendulkar and Saurav Ganguly, who abstained from the camp, were away in the UK. ''They are in England for personal work. They are seniors and know what is expected of them,'' he said.
While Sachin is playing local cricket, Ganguly is by the side of his father, who is undergoing treatment in a hospital.
Players' referral and slow over-rate: Kumble said the proposed players' referral system for umpiring decisions that would be tested in Sri Lanka was new and difficult to comment on.
''This is still in the experimental stage and we have to look at it in Sri Lanka and then only comment on it. This is all new to us, we have to see how technology works in this aspect,'' he said.
Asked whether this would not slow down things in Test cricket when the teams were already struggling to finish 90 overs in a day, he said Test team captains would have to 'move things quickly'.
''Since I have been the Test captain for the last six months, I have not had a problem in getting through 90 overs a day,'' he said.
On Test points system to be introduced in world cricket, he said his team always played with intensity and passion. ''We don't look for points, but go with the same intensity to win against all Test teams,'' he said.
