"We spoke at the start of the tournament that we will assess each one of them and see where they are at and how they feel about their body as the tournament progresses. It is more of an individual thing than what we decided for them," Rohit said.
"How their form is the most important thing, they are really doing well. Anyone who plays the IPL and goes to a big tournament (like the World Cup) I feel it keeps them very much in touch with their game. It is a great tournament to hit form. Hardik is one example," Rohit said.
Talking about the IPL final where Mumbai Indian will be aiming for a fourth title alongside CSK, Rohit said his team is focused on the job at hand.
"It (Hyderabad) is a neutral venue. Both teams have played here so they are very much aware of the conditions. It is not going to be a major factor. Important will be to assess the pitch as quickly as we can, see what the ideal score will be if we bat first," he said.
Mumbai Indian have beaten CSK thrice this season besides getting the better of them in two finals.
Asked if CSK bring the best out of Mumbai Indians, Rohit said: "I wouldn't agree to that. The tournament itself is the biggest challenge, every team is a threat. Rajasthan Royals did not quality but they beat us twice so we have to be good on that particular day.
"There is a lot of hype around the two teams (CSK and MI) and it is because they have been successful in winning the championship, everyone looks forward to the clash."
