Gambhir admitted he was nervous before their match against Pune and attributed their comfortable victory to the allround display of his side.
"Very important two points today. It was a very important game and I was nervous, we had everything to lose today. We needed to be professional. We had come so close we couldn't afford to let it slip from here," he said.
"We needed to be up there, up the energy and if I am asking so much from the team I needed to have that first so I wanted to lead from the front and bring that intensity in the field.
"Credit goes to the entire team. We were never too keen on batting in a hurry for the Net run rate. It wasn't that kind of pitch," he added.
Asked about their next match against Mumbai Indians, Gambhir said, "We want to go out there and look to win the next game as they we would have a very bright chance of moving into the second spot in the table, so that's what we will focus on."
"Jacques' been doing a great job, his injury gave me an opportunity to open today. I want to give credit to the entire bunch of bowlers, everyone bowled well," he added.
Man of the Match, Yusuf Pathan, who scored 29 runs and scalped two wickets, said he was relaxed before the match.
"No tension ahead of the game. Gauti (Gautam) utilised me very well with the ball, I could get wickets and keep the runs down," he said.
Pune Warriors skipper Yuvraj said toss played a crucial factor and reckoned 140 would have been a good score in this pitch which turned a lot in the beginning.
"135-140 would have been a good score. Toss would have been vital, it turned a lot earlier in the first innings and not much in the second half. But credit goes to KKR they bowled according to a plan. we lost too many wickets in between," he said.
Yuvraj said he was giving the youngsters chance to bat up the order so that he can handle the pressure down the line.
"I am happy to allow youngsters bat ahead of me up the order. I have batted for India in tough situation and can handle the pressure," he said.
The left-hander said things didn't work out for his team once again today and it was disappointing.
"It is difficult when you are out of reckoning and you have to play for your pride. Today again things didn't work for us, shots were going to fielders," he said.
Asked about Callum Ferguson whose two overthrows fetched Kolkata two boundaries, Yuvraj said, "All I could do when Ferguson''s throws were going for four was smile, I think this is the best medicine in such situations and so that''s what I did." PTI ATK
