Rahane was the captain during India's series winning Test against Australia at Dharamsala. However, in the Champions Trophy, he did not get to play a single match and had to perform the duties of a 12th man.
But in the West Indies series that followed, he emerged as the top run-getter with Man of the Series award.
"If I am the vice-captain of the Test team, it does not mean that I will not be performing my duties as a 12th man in ODIs. The moment you are representing your country, you are suppose to do whatever you are assigned. When I was carrying drinks during the Champions Trophy, I had no ego issues. That's how I am as a person," Rahane told PTI during an interview.
"West Indies was a special series for me simply for the consistency that I was able to show. This series is an important one for my ODI career and getting runs in almost all the matches was a really satisfying feeling. I got opportunity to show a different side to my batting and express myself differently," said Rahane.

For Rahane, more than technical, there were mental adjustments that were really very necessary.
"And when we talk about discretion, that's where the mind comes into play -- to be able to think clearly what are the shots that I am going to play in a particular situation, on a particular kind of pitch," he said.
For him, what made the knocks special was the pitches in the West Indies which weren't exactly batting friendly with the ones in Port of Spain and Antigua creating difficulties.
The soft-spoken Rahane said that not for once did he feel insecure because he was coming in place of a rested Rohit Sharma, who is again expected to open the innings during the Sri Lanka ODIs.
Although he doesn't want to look too far ahead, Rahane is game about batting at any slot in the limited overs version.
"Actually my spiritual guru tells me one thing. It is very important to live in the present, irrespective of whether you are playing or not. The biggest lesson of life for me is to keep things simple.
On the upcoming Sri Lanka tour, Rahane said that like every Test series, he does his homework and it will be no different this time around.
"I have a few plans for the series and I am working towards it. Obviously, you don't reveal your strategy. Also the Zimbabwe series will not be an indicator that Sri Lanka will be an easy prey for the Indian team. They have some quality players and as opposition, we need to respect them," he concluded.
