Gambhir has been leading from the front by scoring 457 runs so far in the ongoing edition.
"If someone has to change the game, it should be Kallis or me. We don't want (Brendon) McCullum or Yusuf Pathan to change the game. It's our responsibility because we are the experienced guys," Gambhir said at the post-match press conference
"You don't want them to stop playing their natural game. The guys like me and Kallis need to change the game and that is what responsibility and experience is all about."
KKR thrashed Delhi Daredevils by six wickets in a lopsided contest here last night to emerge as the table leaders in the IPL. They now have 17 points and are almost assured of a place in the knock-out stage.
Gambhir said his team is playing in the IPL not just to compete but win matches.
"For me, every game is tough and important. When I go on to the field, I just want to win the match. It's not about competing in the IPL, it's about winning every time. I always look to win matches because you don't want to go back to the dressing room on a losing note. You want to go happy and for that feeling to come, you have to win matches.
"We have some quality players in the dressing room. Someone like Kallis, who is such a legend of the game. Brendon McCullum and Brett Lee are also there. When you have such players, you don't need to motivate them. They all are thorough professionals. One thing important for us is that we need to play well as a unit," he said. More
