Kieron Dyer recognises that sceptics will be ready to write off West Ham's chances of Premier League survival if they lose to Blackpool on Saturday.
Ahead of the visit of Ian Holloway's 2009/10 Championship play-off winners, Avram Grant's Hammers sit bottom of the top flight and four points from safety.
West Ham have thrown away leads to draw their last two matches against Birmingham and West Brom, respectively, to add to the doom and gloom.
And injury-prone Dyer, whose 90-minute outing against West Brom marked a first full game for the club since joining from Newcastle in a £6million deal during August 2007, accepts that things will only get murkier if Blackpool are not defeated.
"We said Birmingham was a 'must win' game, but against Blackpool we need three points otherwise people will start saying we might be doomed," said the midfielder.
"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.
"Again, as soon as we went ahead we nearly got the third goal, but then we kind of went into our shells.
"You could sense it was just a matter of time that they were going to score and it can't be like that.
"As soon as we get in front the attitude is to protect what we have.
"We have got to stop making these mistakes or this is going to cost us dearly."
Former England international Dyer was pleased to be able to get a full match under his belt against the Baggies.
"It was a massive stepping stone. I didn't have much energy for the last 20 minutes - I was running on empty," he said.
"There were no signs of my hamstrings and to get 90 minutes under my belt will help me to get 100 per cent match-fit."
