Chris Hughton has been warned by Norwich's chief executive, David McNally, to keep them out of the bottom three of the Premier League or face the consequences.
The Canaries remain in a relegation battle and sit just one point above about the drop zone following their 2-0 defeat to West Ham on Wednesday - leaving them with just one win in 11 games.
McNally insists that the Hughton still has the full boards support but admitted the situation remains constantly under review in a "results business".
In an interview with BBC Radio Norfolk and Archant, McNally said: "We are too close for comfort. Chris has been told in no uncertain terms 'get us out of that position and keep us out', but equally, we're three points off 10th.
"As far as giving any certainty for Chris, or anyone else - it's a results business. Whether that's Chris Hughton as manager or me as chief executive or anybody else, we're paid to do our jobs.
"As long as we achieve what is required of us, then we'll stay in work. It would be wrong at any level, delinquent almost, to give any guarantees. All I would assure Norwich supporters is that we are watching it very carefully. The whole board is aware of the strength of feeling from the support.''
Norwich who spent in excess of £20 million last summer on new recruits, have struggled to score goals with just 19 in the league and club-record £8.5m signing Rick van Wolfswinkel hasn't scored since the opening day.
"I know, having invested in the summer, the supporters expect us to be in a higher position, which is a natural conclusion considering this is our third season in the Premier League," McNally said. "Last season, we finished 11th. We had the 20th biggest payroll.
"I know Chris is working hard to do what we need to stay in the league and move up the table. He's 100 percent positive he will do that. So he has the support of the club to go on and ensure we get the points to achieve those objectives.''
Hughton was appointed in 2012 replacing Paul Lambert in the dug-out but is starting to feel the pressure.
Fulham are the latest club to sack their manager after letting Rene Meulensteen go after 75 days in charge following just four wins in 17 games.
