Sam Allardyce admits he fears Crystal Palace will plunge into a relegation crisis.
The Eagles sit 17th on the Premier League table with just 16 points from 21 matches, equal with 18th-placed Hull City.
Since Allardyce replaced Alan Pardew at Selhurst Park just before Christmas, Palace have lost three and drawn two of the five fixtures the former England bass has been in charge of which has prompted fears for the worst.
"I am scared that we won't succeed. Definitely," he said.
"The last thing I want is to say I've come here and not been able to save Crystal Palace with a track record which has never had that blemish on it since I've been in the Premier League. I don't want that.
"It's a hard task to take on, but I'm willing to go on at it and use all my experience I have gained in the past to say to the players: 'look, I've been here before, this is what we need to do'.
"It always scares you when you first come in (to a new managerial job).
"I'm not fearful of losing my job; it's the fear of not wanting to blemish my record and helping Crystal Palace get out of trouble when it has stayed in the Premier League so long recently.
"What we have to do is see ourselves through this crisis. Let's face it, we are in crisis mode. We've got 16 points from 21 games and we won't feel comfortable until we've got the same number of points as games.
"I'm good at it. On my track record I've proven that but there are so many elements that make life difficult for you. At the moment, the price of players, too many injuries, the African Nations Cup."
Palace were beaten 3-0 by Big Sam's old club West Ham United at the London Stadium on Saturday. They next take on another of Allardyce's former clubs in Bolton Wanderers in a FA Cup third-round replay on Tuesday.
