Reports this week claimed the under-pressure Dutchman was talked out of standing down at Old Trafford following a meeting with chairman Ed Woodward.
Van Gaal claims that is not true and turned his anger on the media for how they have portrayed him during United's troubled run of form.
Asked if he had offered to quit, the 64-year-old said at a press conference: "I don't think that I have ever mentioned it.
"I think you make your own stories and then I have to answer about your stories, and I am not doing that because it is awful and horrible that you can write that and then I have to answer the questions of your story.
"I am very concerned people are believing what you are writing
I receive a lot of calls and SMSs, but it is this world that you can write what you want and you don't have to verify anything.
"It is now the third time already that I have been sacked, and I am still sitting here for you."
