Kieron Dyer accepts West Ham could well appear "doomed" if they do not beat Blackpool at Upton Park on Saturday.
Avram Grant's men remain bottom of the Barclays Premier League following the 2-2 draw with West Brom at Upton Park.
Grant continues to command the backing of co-owners David Sullivan and David Gold, but for how long remains to be seen.
West Ham - four points from safety - have now not won in the league since September 25 and Dyer accepts another failure against the promoted Tangerines and things would look bleak.
"We said Birmingham was a 'must-win' game, but against Blackpool we need three points otherwise people will start saying we might be doomed," the midfielder reflected. "Blackpool are going to come here and have a right go at us.
"We have to be confident and match their desire. It is all about playing with no fear. I am a confident player and I don't let things affect me but you can see that some players are affected."
