Sunderland are currently five points adrift of safety, and are still looking for their first win of the season.
Charlie Nicholas has warned on Sky Sports' Soccer Saturday that Sam Allardyce will leave Sunderland just as quickly as his predecessors if he is unable to stop them drifting towards the drop and does not receive the required backing in January.
And, although Allardyce's appointment has increased the levels of optimism around the Stadium of Light, Nicholas feels that the 60-year-old manager needs to spark an immediate improvement in results, and be given license to invest in the next transfer market, otherwise his stay on Wearside will be brief.
"Allardyce has to get it right from now until January to see himself through here," he said. "The reality of where they are, is that if they don't pick up anything up in the derby next week [they're in trouble].
"It's fine Allardyce saying that 'they all want me, and I won't get the pressure and the stick', but the reality is that he has to keep this team in with a chance until January.
"Then in January, he has to say 'I don't care, who's on your committee. I am responsible for this job, and I will make these decisions'. If they don't do that, Sam will go just as quickly as all the other managers have gone."
Allardyce takes over at Sunderland looking to pick up where Gus Poyet, Paolo Di Canio and Dick Advocaat have all failed.
The North East based outfit have been in a constant struggle against relegation for the past few seasons, and they seem unable to make any progress.
Allardyce will be hoping that he can start guiding them up the Premier League table, but doing so looks a tough task.
Sunderland have been well off the pace over the early part of the season, and only a serious improvement in their performance levels will see them pick up enough victories to get them out of trouble.
