Owner Mike Ashley missed the defeat as he enjoyed a winter break, but Sunday's FA Cup third round trip to Coca-Cola Championship Stoke is assuming ever greater importance.
Chairman Chris Mort has insisted the club is not actively looking for a replacement, and while that support is welcome, Allardyce knows results have to improve drastically is he is to get the time he needs to turn things around.
Allardyce said: "The support is great, but at the end of the day, the pressure still mounts, it mounts despite that support.
"It mounts on us all, but on me in particular because we have lost a game at St James' Park we should not have lost.
"Now it is three defeats on the trot. The pressure grows because a team like us should not be losing at home, a team like us should not be losing three games on the trot.
"We have got to stick together and believe that how we can play can get us out of trouble. That starts at Stoke."
