"2002 was different," the 36-year-old said in an interview with the Times of India.
"We were a young team, no one expected us to reach the final. But in the end we did. Still it feels really awful to lose a final, so it's our time to win this one now.
"For us, team spirit is not an empty expression. No one bears any animosity. They are all very professional and mature, even if some of them are only 25 or 26, some even younger. We are a team, a close-knit unit. We win and lose together.
"We enjoyed the game against Brazil but we ticked it off after 24 hours. Sadly, it was only a semi-final, as in the next game against Argentina, we have to again play to the best of our abilities.
"I am just looking forward to an exciting game, which will be marked by tactics and a bit of trickery. A repeat of the Brazil game is not on the cards."
Klose became the World Cup's all-time top scorer after his goal against the Selecao, having now scored 16 times over the course of four tournaments, but he confessed that the achievement would mean little if he finished as a runner-up once more in the tournament.
"It's a hugely emotional thing for me personally," the Lazio forward said of the record.
"But people who know me, know that my focus is already on Argentina -100 per cent!
"Yes, I have overtaken Ronaldo as the highest scorer in the World Cup but that is something to take on board another day. If we lose the final, my joy will be significantly dampened.
'If we do win the trophy, I can imagine that I will relax. There is a party beast somewhere even in me!"
