Owen Coyle expects his Bolton side to be involved in a survival battle until the very last day of the Premier League season.
Wanderers' three-game winning run came to an end as they slumped to a disappointing 3-0 home defeat at the hands of Fulham on Saturday.
But Coyle felt his side missed a golden opportunity to stay clear of the bottom three and expects Bolton to be involved in a relegation tussle in the remaining games.
"We under-achieved (against Fulham) and let ourselves down, no doubt about it," admitted Coyle.
"It is a setback and of course we are disappointed, particularly at home.
"Our home form had been very good of late and we were looking to capitalise on that.
"It is not a nice feeling as we were coming into the game after three straight wins, we were at home and looking to open up a gap in that area of the league we are in.
"But it has happened to us before - we have to pick ourselves up and prepare to go again. That is what we will look to do."
Coyle did take some consolation from the failures of relegation rivals Wigan, Blackburn and Wolves to win.
He said: "It's been similar to previous weeks when teams have won and we have won. That's why it's such an intriguing league.
"I have said before that it will go right to the wire, both at the top and bottom.
"That is why it is the best league in the world and we have not done ourselves justice in that league here.
"The fans came in huge numbers again and I feel for them because they deserved a better performance than we delivered."
