Reading currently sit second bottom in the Premier League, still without a win. Most concerning has been the club's tendency to drop points from winning positions, drawing against Swansea and Newcastle and losing to Chelsea despite being ahead.
Although there has been no official vote of confidence, McDermott is aware that his side need a win sooner rather than later if they are to avoid a relegation battle, as rumours suggest he is under pressure.
"I cannot affect speculation and who says what.
"All I know is I've got great staff, my director of football is fantastic and I've got a great bunch of players who do the best they can on a Saturday afternoon.
"What more can we do? That's it as far as I'm concerned."
McDermott also dealt with speculation that new owner Anton Zingarevich has been too heavily involved in the affairs of the team, confirming that the Russian had never forced him to explain the team's results or performances.
"I've had no reason to make a case like that, I speak to him regularly.
He added: "I don't need to speak to him about that, he can see for himself."
