Klose hit a brace in the 4-2 win.
"It's an important victory. We worked extremely hard in the first half and deserved [the win]," Klose said.
"I've been at Lazio for three years and see the work we do on the pitch. We wanted third place and we have demonstrated this.
"We go game by game, but we want to finish at least in the top five.
"Do I want to play more? Everybody wants to play, but all of us can make our mark. As always, the Coach decides."
