"I will never put my ego before the team," Klose told German magazine Kicker. "I have never done, and will never do so."
The 34-year-old started his first game of the tournament in the quarter-final against Greece, where he scored a second-half header to make it 3-1.
But the Lazio striker was frank in his assessment of the competition so far, and agreed that coach Joachim Low had a difficult choice to make between him and Mario Gomez.
"I do not feel right, though, as a player [on the bench]," Klose explained. "The coach and I have done some interviews, but we will exchange our views in the open."
He added, "Ultimately, he has a choice between two top strikers. That's a gift for him and for the team."
And when asked if he believed he could make the squad for Brazil 2014, Klose was optimistic.
"That is possible," he replied.
Joachim Low's side play Italy on Thursday for a place in Euro 2012 final.
