Hibernian manager Pat Fenlon said he was left "disgusted" by his players' attitude and work-rate in their 2-0 loss to Queen of the South in the Scottish Communities League Cup.
Goals from Nicky Clark and Gavin Reilly gave the Second Division side a famous victory at Palmerston.
Fenlon made several changes to his line-up, leaving out captain James McPake.
However the Irishman laid the blame at his players, saying: "I'm disgusted by that performance
"We have let ourselves down and let down a fair few supporters who have travelled a long way.
"We just didn't treat it properly, we didn't get to the tempo we should have.
"They worked harder and I thought they were very good, they passed it when they had to and turned us round when they had to and just were better than us all round.
"It's about attitude and application when you come to places like this. If you don't apply yourselves properly you will get turned over. I told them that [on Monday] and I told them that again.
"All round the park, the application from their players was much better than us."
Shefki Kuqi came in for Eoin Doyle while Sean O’Hanlon replaced McPake in defence while Pa Kujabi and Callum Booth were taken off at half-time
Fenlon said: "We didn't rest them, we tried to change the team around and freshen it up.
"But if we can't make three or four changes and not come down here and win, without being disrespectful to anyone, we have to have a look at things."
