Aguirre is ready for his team's crunch match against the champions on Sunday, the game that will decide whether or not the Madrid-based minnows can avoid relegation to LaLiga SmartBank.
"We will try to do what is in our hands and that is win the match," Aguirre said.
"The rest depends on others and if we don't survive, we can't ask anyone for anything if we don't succeed. Humility is what defines this team."
Leganes' opponents on Sunday couldn't be trickier, something the 61-year-old recognises.
"Madrid are an all-time great team," Aguirre noted.
"They have the winning formula, they will be going for the most victories in a row, Benzema for the Pichichi... They won't relax at all.
"I expect the same Madrid as always, the best Madrid.
"I don't have clear highs and lows and I can't talk about assumptions."
