Birmingham City boss Alex McLeish felt let down by his players after they lost 2-1 at Huddersfield Town in the third round of the FA Cup.
The Blues were beaten by Chris Brandon's volley nine minutes from time for the Terriers, with McLeish disappointed by a lacklustre display at the Galpharm Stadium.
He said: "The Premier League is our priority and it remains our priority, but we wanted to win this match, no question.
"I've been involved in cup upsets as a player and a manager. I've been a giantkiller, but I've seen the other side and I didn't want to be a victim.
"The players will be embarrassed by it because they'll get bad headlines and so will I. That is the position we are in.
"The dressing room chat remains private and that is where it must stay. But every one of our players can look in the mirror and say 'we've let ourselves down and let the fans down'.
"We had three or four internationals out there and we should be better than that."
