Sean Dyche conceded that Fulham were the better side as the Clarets were sunk on the banks of the Thames.
The Cottagers ran out worthy winners to register their first victory since returning to the Premier League.
And the Burnley boss admitted his players deserved nothing after dropping below their usual high standards.
Dyche said: “They were the better side for most, if not all of the game and there were signs that they have invested the £100m well.
“Some of their pockets of play were very good and they got off with a good goal. It’s hard to question the players too much for that and we reacted well and got a good goal through Jeff.
“I’m pleased for him because he’s been a bit of a shining light for us with his performances.
“But then we gave away two awful goals, very quickly. After getting another back we were still in it and we remodelled it slightly at half time with Johann going off (hamstring injury).
“But I never try to call it anything other than honest and today they were the better side.”
The Clarets fell behind early on through a rocket from Jean Michael Sari, but equalised soon afterwards through Hendrick’s first goal of the season.
Two goals from Aleksandar Mitrovic in as many minutes, just after the half hour, put the Clarets on the back foot, before James Tarkowski immediately recused the arrears.
But in a tighter second half, the game was finally decided by Andre Schurrle’s effort nine minutes form time, despite Joe Hart’s best efforts to deny Mitrovic a hat-trick.
Dyche added: “We didn’t find the quality and I know these players. I see them in training and the quality they have in the front third and today we were not using our quality.
“The bravest part of football is the front third and that’s where you need the moments of quality and the clever play and movement and belief.
“We have to work on that, but while you are doing that you have to keep the back door shut and we didn’t do that well enough either. If you get those two things wrong, it doesn’t bode well.
“They were braver than us in the front third and their centre forward (Mitrovic) was the best player on the pitch.
“That’s helpful of course, but he was the best player by a long shot.”
Dyche added: “They played a way I want to and that was effective. They stretched us when they had to and played when they could and that’s certainly what we’ve been working towards all these years, although there weren’t too many signs of it today.
“But we know the challenges around us and we knew all about the noises outside the club about the Europa League and how that is going to challenge us.
“It is difficult for the players because they have been bombarded with negatives about the challenge it presents.
“But we have to see beyond that and the players need to understand that today, that’s dropping below our levels and we have to get back up to them because we are a good side, as we showed last season.”
