Nottingham Forest boss Steve Cooper appreciated the support from away fans after their 5-0 thrashing by Fulham.
Alex Iwobi and Raul Jimenez both struck twice, with Tom Cairney also on the scoresheet on the night.
On the support, Cooper said: "It means so much but I'm personally embarrassed, I'm grateful, of course, but I don't deserve that [support].
"Regardless of who is playing, who the manager is, you can't let these people down like that - you just can't.
"We've shown over the last few years how important this club is to the city and the joy that it has given, so to not represent it in the way that it should be is hurtful. I take responsibility for that.
"I didn't deserve that tonight from the supporters - we all let them down and we have to take responsibility."
Cooper added: "[It is] painful, and painful in so many ways. It's a result we have to accept is our fault and we deserve.
"It's on the back of technical and tactical failings. On top of that, not enough desire or will. [Desire] is not something I questioned before.
"Tonight we lacked everything to have any chance of success in the game - we fell short in so many ways."
