"I know how it works at top clubs, it is results that count," the 59-year-old former Barcelona and Netherlands coach told reporters when asked about the risk of being sacked if Bayern lost.
"I can live with that and can handle it. It is normal," he said. "I do feel sorry for my staff because I am going towards the end of my career."
Van Gaal's first season at Bayern was ended in triumph with a domestic double and a Champions League final spot last year but Bayern have struggled this time round.
"I have not been sacked that often and have stayed long at my clubs. I am proud to be working at Bayern," Van Gaal said.
"If we win on Saturday then we are in third place and can still achieve what we have set out. Then the world will look differently," he said.
