Meanwhile, Dhoni came up with a skill that surprised many. The veteran was seen practicing leg spin in a video, posted by the official Twitter handle of IPL.
Within no time, this Tweet was shared several times. Some of the fans asked whether the former India skipper wanted to add a "third dimension" to his game.
Dhoni missed two games for CSK this season due to fever and stiff back, and on both occasion they ended on the losing side.
Asked Raina how challenging it was to lead CSK in Dhoni's absence, he replied: "I think losing him (Dhoni) as a captain is not an issue, losing him as a batsman is always difficult for us. That's what happened for us against Hyderabad and Mumbai Indians.
"When he comes to the crease a lot of pressure is created for other teams. When he is not in the team, we see the difference."
