It has been reported the Serbian, who was appointed in December 2015, has delayed discussions about extending his commitment to the London club, who he guided to promotion via the play-offs last season.
Asked about his contract situation, Jokanovic said: "This is not the first time I got this question and in general I prefer not to make contact about private things.
"This is job is in the hands of my agent and the club. When I have some kind of news I can share, I will share with all the people.
"In this moment, I am focused only about the Premier League, about competition. I am fully motivated to be successful with my team and this kind of situation is in the hands of different people.
"I am really not talking all day with the club about money, or the situation. I am working on the pitch.
"I know I depend on the results and our supporters, after two games, will expect some points.
"What I am really worried about is my team, about results, about getting our first Premier League points. That's where I'm focusing my energy."
