Andy O'Brien believes 40 points will be good enough to keep Bolton in the Premier League.
Gary Megson's side has been marooned on 25 points, suffering three successive league defeats since beating Reading.
A 50 per cent points haul from the remaining 10 matches should be within Bolton's capabilities.
"People usually say if you get to 40 points you will be safe," O'Brien told the Manchester Evening News.
"And I think if we get that total we should be all right. But it's not going to be easy."
