The much-anticipated match between these team's has been described as a revenge match for Ganguly, who was dropped by the Knight Riders and remained unsold in the auction after three seasons with his home side.
But the Pune Warriors brought Ganguly back in action, appointing him as skipper , he will lead the visitors side for the first time at his home ground Eden Gardens.
"It's just the media that is creating the hype. For me, it's just another game of cricket. Sourav is an individual. We are playing against Pune Warriors and not against Sourav Ganguly," Gambhir said on the match eve.
"Whoever Kolkata wants to support they are free to support. I have always maintained KKR belongs to Kolkata. There is no other team that belongs to Kolkata," Gambhir said.
"We always play for the pride of Kolkata. We will always do that, whether we get the support or not. We go out there to make people happy and bring joy to them. Our job will be the same whether we would be the away or home team tomorrow. We will keep playing for Kolkata be it tomorrow or near future," the left-hander said.
Kolkata bowling consultant Wasim Akram had termed this tie similar to India-Pakistan clash, but Gambhir refused to agree.
"We are playing against Pune Warriors and there is no such rivalry as Pakistan. India and Pakistan is a completely different ball game," he said.
"That's his (Akram's) view of looking at the tomorrow's game. For me, it's another game of cricket. There is nothing so-called India vs Pakistan."
"It's important to certain extent. To win a game you need to play well on that given day. I've always maintained that it's just another game of cricket. We will approach the same way as we have approached all the other games.
Ganguly may be struggling with a four consecutive losses compared to Kolkata's recent winning form, but Gambhir said were not being complacent.
"In T20 format, it's just a matter of time. One or two matches can turn the fortunes. It's such a format, you can lose seven or eight games in a row and yet can end up winning eight games in a row as well. Four losses in a row will not make any difference."
"We need to play well and concentrate on our strategy rather than thinking about what opposition are doing. As I said we are not playing against individuals we are playing against a team. If individuals are struggling that does not make them a lesser force. Any one of them can fire with the ball or bat and can win the game," he said.
Despite their star-studded line-up, Gambhir's XI are yet to play to their full potential this season.
"Let's talk about the team performances rather than the individual ones. KKR is not about Yusuf Pathan, Gautam Gambhir or Jacques Kallis. KKR is about what we have done as a team," he said about their four-match winning run to be comfortably placed second in the table.
"I am not concerned with any form or anything. I'm pretty happy with the performance till now and that's what we are looking to do in future as well.
"We have got some finishers. We have got a lot of depth in our batting. Someone will get the opportunity to finish the game tomorrow as well. It's not how you start, it's about how you finish as well," he said.
When figured out that it's the spinners who have been outstanding for the side, Gambhir was quick to point out Kallis' spell of 4-0-21-2 in their five-wicket win over Chennai Super Kings in the previous outing.
"It's not only the spinners who have done a job for us. Kallis did a tremendous job for us in the last match. Everyone's done a great job for us. The overall bowling department has done a great job for us."
Asked to predict a winning score on Saturday, Gambhir said, "I don't predict things. If we bat first we will try to get as many as we can. And if we bowl, then we will try to restrict the opposition as less as we can. For me no total is safe or no total is less as well. We need to go out there and play to the potential."
