The two sides meet in the third Test starting on Thursday after India took a 1-0 lead in the second Test which ended in Kolkata on Sunday.
"I don't need to stress how important this match is for us. We have to take a simple approach of winning at all costs. We have to be aggressive and positive," Inzamam told reporters.
"I never thought I'd play 100 matches, but tomorrow is the day. If we win it, it'll be extra special. It's not been an easy journey since 1992, but it's been thoroughly enjoyable."
Pakistan have little choice but to rely on Inzamam for another of his match-winning knocks with the bowlers struggling in the absence of pace spearhead Shoaib Akhtar and the batsmen failing to deliver under pressure in Kolkata.
Indian captain Sourav Ganguly paid tribute to Inzamam.
Inzamam, who said the 1992 World Cup win was the most memorable moment of his career and his poor form in the 2003 edition, when he scored just 19 runs, his worst said there would be at least two changes in the side.
FLAT PITCH
Opener Yasir Hameed is expected to come in for Taufeeq Umar and spinner Arshad Khan for left-arm paceman Mohammad Khalil on a flat, brownish pitch which looks good for batting.
"The toss is very important on flat wickets. On this track, whichever team bats first will have a huge advantage," Inzamam said.
India will probably go into the match with the same 11 who played in Kolkata, with Harbhajan Singh available despite being reported to the International Cricket Council (ICC) for throwing for the second time in three months.
"I think we all need to know where the ICC stands on Harbhajan," Ganguly said. "He's a great spinner with a long career ahead of him and he needs to play without all this pressure."
The Indian captain said his team would not let up even though they were sitting on a 1-0 lead.
"We have to try to win, playing with the same mindset we had in the first two Tests," he said.
If India win the match they will overtake England as the second-ranked team in the ICC Test rankings behind Australia.
