Tendulkar is locked to 99 tons (51 tests and 48 one dayers), because the 50-over World Cup this year, and his fans waiting to reach the goal at home against the attack of the West Indies is not free from limitations.
"We let go of the century, and then talk about it. I hope it gets here (first) game and talk about the fifth day," Dhoni said after practice Saturday at the Feroz Shah Kotla Stadium.
"It's a milestone Sachin will achieve, whether in this game, the next game or some other games. It's inevitable.
"So instead of talking too much away from the next stage in what we do is we said," Ok, that makes tons, and then we'll talk. "We are considering how to prepare for the series.
"Of course, gets a ton, we all celebrate with him. It 'a great moment of Indian cricket."
Dhoni is due to the severity of his determination to lead the ranking of India in the early test after England Dethroned are 4-0 whitewash in August.
"We want to be the best in the world, but it is not something that belongs to you. You need it, you must keep well.
"We're not very well in England so it is not the number one team right now. Again, it is a process and reach the top of the world must follow the process.
"Start a second trial for us and we hope we are focused enough to do well, there again and try to keep it."
With the pace spearhead Zaheer Khan recovering from ankle surgery and high-spinner Harbhajan Singh fell, India will rely on a relatively inexperienced attack to get the 20 wickets in each match.
Dhoni said at least two players, probably an off-spinner Ravichandran Ashwin, Umesh Yadav, and is another step or any bowler Aaron Varun, make a test debut on Sunday.
And the team will ensure that they do not get too excited, Dhoni said.
"It's not a difficult thing, because if you see bowlers who have been selected, most of them have played the ODI format, which means they have a reasonable amount of exposure when s' acts of international cricket.
"So I do not think they will be really excited.
"Of course, if we see something to do there are the best players to come to their rescue and help."
