Dhoni, who led the CSK to a third title triumph in the 2018 edition, trained with Ambati Rayudu and Kedar Jadhav, who were part of the Indian team that played a five-match ODI series against Australia recently.
Dhoni, Rayudu, Jadhav, Raina and the others batted at the nets under the watchful eyes of Fleming and Hussey.
The domestic players in the squad, including Karn Sharma, KM Asif and Tamil Nadu 'keeper N Jagadeesan began training on March 6.
The foreign players in the CSK squad are expected to join the training camp in the days to come as would South Africa captain Faf du Plessis and leg-spinner Imran Tahir, who are part of the squad that is playing the final ODI against Sri Lanka at Cape Town today.
Hussey, who was supervising the first day of the full-fledged training, said with a team like CSK there are always expectations and added that they can take a lot of confidence from the last season.
"With a team like Chennai Super Kings there is always expectations but I think we can take a lot of confidence from the last season going into the new one," the former Australia cricketer was quoted as saying on the CSK website.
He also said the team hoped to play more matches in Chennai this time after it was forced to rebase to Pune last season owing to the political climate in Tamil Nadu due to the Cauvery river water dispute.
"Hopefully, we get plenty more games in Chennai as well, in front of our home fans who we often feel are an extra fielder for us," Hussey added.
Meanwhile, sale of tickets for the first game of IPL-12 between CSK and Virat Kohli-led Royal Challengers Bangalore on March 23, began today.
According to sources, tickets for the tournament opener were sold out.
