Allardyce believes that a point-per-game average will be enough to secure the club's top-flight status and he is eager to achieve that tally as quickly as possible, with Hull City the visitors to Upton Park on Wednesday.
"We never said or suggested that we were safe when we were on the fantastic run and we've got sucked back towards it again," he added. "We need 38 points and we'll want to go past that as quickly as possible.
"We've had a couple of lapses in concentration that the opposition have taken advantage of in the last three games."
