Sunderland boss Martin O'Neill insists he is the right person for extracting the Black Cats out of their current relegation-battling troubles.
The Black Cats are third from bottom of the Premier League and face fellow strugglers Reading on Tuesday.
O'Neill said: "So what do you do then? You go and put someone else in charge, he gets a group of 12, 13 games and can't win any? It's the same thing.
"I don't want to be boastful, but not only am I the best man for the job, I am actually the only man for the job."
They have won just two of their last 23 Premier League matches and doubts have emerged over O'Neill's position.
"We will steer through it, we will get calmer waters ahead - it might take us a few months to do that - and then we will see," added the 60-year-old.
But O'Neill will look at his role if the Black Cats' current run continues past this season. He said: "If we are continuing for the next couple of years to be in this position, I will certainly question it then."
