The Dutchman has been linked with Brian McDermott's job at Reading.
Asked directly about Advocaat, who once coached Zenit St Petersburg, the team Zingarevich supported growing up, he told the Daily Mail: "I don't even know where that came from. That's what speculation is, right?
"When the results are not going your way, especially where there's so much attention, it gets a little bit more difficult. But I'm sure Brian is the man for the job."
