Ryan Nelsen believes the Queens Park Rangers squad have fallen well short of expectations during the early part of the season.
Mark Hughes brought a number of fresh faces into Loftus Road over the summer, with an ambitious rebuilding project intended to help steer the club clear of trouble.
They are, however, yet to record a victory seven games into the new Premier League campaign and remain rooted to the foot of the table.
Nelsen, who admits performances have not been good enough, said after Saturday's 3-2 defeat to West Bromwich Albion: "We have to live up to expectations. It's our livelihoods, we have to win games.
"It takes time to gel and injuries to players in key positions haven't helped.
"The only real bright spot for us is that at least this run is happening now. There's a long way to go yet.
"But we know each and every one of us have got to be a lot better. We're letting the manager down here.
"We just have to win matches. I think every player has let the manager down at some stage this season."
A slow start proved costly once again against West Brom and Nelsen acknowledges that QPR need to become more resilient if they are to start picking up points.
"Teams aren't really earning their goals against us to tell the truth," he said.
"We have to start from 20 yards behind all the time. We have to remedy that and as soon as we do it'll be a lot easier to get ourselves up to win games.
"Unfortunately, we have had injuries to our wide defenders, but I don't want to make excuses."
