Gambhir also welcomed the inclusion of Yuvraj Singh and Harbhajan Singh in the squad.
New Delhi: The Indian selection committee of late has been playing the game of 'musical chair' by rotating the post of vice-captaincy between Gautam Gambhir and Virat Kohli but the former seemed unperturbed after being handed back the position for the World T20 in Sri Lanka.
"Your responsibilities and commitment towards the team don't change with change in designation. I am not in the team for my vice-captaincy. I am in the team to score runs and win matches for my country," Gambhir retorted when asked for his reaction after being reinstated as Mahendra Singh Dhoni's deputy.
Gambhir welcomed the inclusion of Yuvraj Singh and Harbhajan Singh in the squad.
"Yuvraj has been a match-winner and it is great to see him back in the team. As to whether the mood of the dressing room will be upbeat with Yuvraj coming back, I believe it's not dependent on any particular individual. It is about collective effort which constitutes of each and every member of the team," the left-hander said.
On Harbhajan, Gambhir said, "I am happy that Harbhajan is in the squad because in big tournaments, you need players like him. It's just not like that he has played 98 Tests and 229 ODIs. He is a big-occasion man."
He seemed a bit miffed when a scribe asked whether Piyush Chawla is in the team because he is a "lucky mascot" for World Cup squad, having been a part of the 2011 team.
"I have never believed in luck and lucky mascots. For me, there is only one thing that can ensure you success at the highest level -- that is called hard work. I will always remain a firm believer that there can't be any substitute for sheer hard work."
The senior opener admitted that his recent string of good scores in Sri Lanka will act as a morale booster, but that will be of little consequence when they play the World Twenty20 in the island nation.
"World T20 will be a different ballgame altogether but we have played so many times in Sri Lanka that we are aware about the conditions over there."
Talking about the necessity to adapt while having to quickly switch formats, Gambhir said that the two T20 Internationals against New Zealand will be crucial.
"Yes, we will be playing Test cricket next but then we will be playing a couple of T20 Internationals. Also once, we reach Sri Lanka, we will be playing a few more practice T20 games. Before the tournament starts, we would have played four to five T20 matches and that would serve as good enough preparation for the World Cup."
Gambhir was confident that the younger crop of Indian players would make full use of the opportunities, which they would be getting due to Rahul Dravid's retirement.
"It's not easy to replace someone like Rahul Dravid. But if you talk about how life will be without Dravid's presence in the dressing room after 16 long years, then the same question would have arisen when greats of yesteryears had also retired. I wish, whoever replaces Dravid, is able to make full use of the opportunities," he stated.
Gambhir didn't name any particular player as to who he thinks would be an ideal No 3 batsman in Tests.
"We have lot of talented batsmen. It can be Virat, Ajinkya Rahane or Cheteshwar Pujara all of whom have done well."
