Newcastle United boss John Carverr understood fans jeering after their FA Cup defeat at Leicester City.
Leonardo Ulloa's first-half header was the difference between two much-changed teams.
Carver said: "The fans pay their money and they are entitled to do that and react that way.
"It's hugely embarrassing but they are entitled to do that. One thing I was going to make sure I do was make sure the players did go over. I wasn't going to shirk that responsibility and I wanted to make sure the players didn't either."
