The 36-year-old became the competition's most prolific marksman of all time on Tuesday by scoring his 16th tournament goal in the 7-1 thrashing of Brazil in Belo Horizonte.
However, Klose claims that such an achievement would pale into insignificance if Germany lose to Argentina in Sunday's final at the Maracana.
"It's a hugely emotional thing for me but people who know me, know that my focus is already on Argentina – 100%," he told reporters.
"Yes, I have overtaken Ronaldo as the best goal-scorer but that is something to take on board another day.
"If we lose the final, my joy as the top-scorer will be significantly dampened."
Sunday's showpiece in Rio kicks off at 8pm.
