Fulham boss Martin Jol insists his side's self-belief has not been shaken ahead of their Boxing Day derby with Chelsea.
The Cottagers were thumped 5-0 at home by Manchester United on Wednesday night, contributing to what has already been an inconsistent start to the season.
But Jol believes Fulham can rediscover the defensive solidity they had shown before the United drubbing, when the champions led 3-0 at half-time before claiming two goals in the last three minutes.
"I don't think we are lacking confidence, it's about teamwork," said the Dutchman.
"If you work as a team, we are good, and our goal difference has shown that.
"That's probably been a big plus for us this season, but that is something we destroyed on Wednesday with the five goals.
"If you concede early like we did, then you get tired as well and that's not what you want.
"In the second half we showed we wanted to play for ourselves, the team and the supporters. We could have got back into the game had it been 3-1 because we had chances, but it wasn't to be."
Jol hopes to make amends on Boxing Day and what better way than getting a positive result at the club's West London rivals.
"It's a good opportunity to show everyone that we can defend better," he said.
"If we don't defend better we'll never win a game against a top side.
"It does not lift your confidence if you get a defeat like this, so you have to do a lot of talking for resolve.
"We've learned from this. We have to do better, be more aggressive, and if we have the ball, we must take the game to them."
