"It is not always the club that has to sack me," said Van Gaal.
"Sometimes I do it by myself. I am the one who wants to speak first."
United are currently suffering their worst run of form since 1961, with their last victory coming against Watford on November 21.
The Red Devils will be hoping to get back to winning ways against Chelsea, a side who have also struggled to impress this season.
Former Blues boss Jose Mourinho is waiting in the wings should Van Gaal leave his Old Trafford post in the coming weeks, while assistant manager Ryan Giggs has also been tipped to take over the reins.
It's not all doom and gloom for Van Gaal as Bastian Schweinsteiger is available for selection after serving a three-match ban.
Right back Matteo Darmian could also feature after missing the last three games with a hamstring injury.
