Nigel Reo-Coker believes Bolton let themselves down in the 5-0 hammering by Manchester United on Saturday.
Bolton suffered their heaviest home defeat in 15 years as in-form United, and especially hat-trick hero Wayne Rooney, ran riot at the Reebok Stadium.
Summer signing Reo-Coker insists the players are to blame for the showing and not Bolton boss Owen Coyle.
"The bottom line is we weren't good enough," admitted Reo-Coker. "We didn't apply ourselves correctly.
"We have got no one to blame but ourselves. The manager hasn't got to take any blame. It's the players who must take full responsibility.
"We just weren't good enough. United did play well and that's why they are champions and have won 19 league titles.
"You should not give world class players that much time and space in certain situations. If you play one of the best teams in the world and show them too much respect they will run all over you and that's what we did."
Reo-Coker believes they must learn their lessons from the defeat ahead of this weekend's home clash with Norwich.
"Lessons must be learned," added Reo-Coker. "We cannot let it happen again.
"It's a new team, it's a new start and we weren't good enough. It's nothing to do with the manager. We have to take full responsibility.
"The manager backs us 100 per cent and gives us opportunity to play and we didn't do that."
