Leicester boss Nigel Pearson lamented his side's performance as they crashed out of the Capital One Cup to League Two outfit Burton Albion.
The Foxes were beaten 4-2 at the King Power Stadium on Tuesday night after Pearson made eight changes from the team that lost 2-1 at Blackburn last Saturday.
The former Hull City manager could not hide his disappointment and anger.
"It was an awful result and an awful performance.The side should have been good enough to negotiate that cup tie, but we ended up being embarrassed," he said.
"We had a number of players who missed the opportunity to perform on the big stage. It was a very bad night for us. But the biggest disappointment is the fact we have not won the game.
"I know I made a number of changes but we we had players who felt that had not had the number of opportunities they would have liked so far. A number of then had the chance in this match and they have clearly not taken it.
"There is no hiding place from a result and performance like that. I am the manager and I will take responsibility.
"I am angry as well as disappointed because the team's performance reflects on me, and I am not happy about that at all. It was an extremely poor performance and we are not proud about it."
Chris Palmer gave Burton a first-half lead and Cleveland Taylor's volley put them two up in the 52nd minute.
Anthony Knockaert pulled one back for City with a free-kick but Robbie Weir, with a penalty, and Jacques Maghoma made it 4-1 before Marko Futacs snatched a late consolation for the Foxes.
Burton manager Gary Rowett was dleighted with his side's display.
"We set out with a game plan and had just one up front because we needed an extra body in midfield," he said.
"We rode our luck at times and and the goals came at the right time for us.
"But there were some excellent individual performances and it was a fantastic result for us. A terrific win.
"There is no extra pleasure for me because it is against a former club, because I like to see my old clubs doing well.
"We had to work really hard for everything and we needed to ride our luck and take our chances. We stuck at it and kept believing and there was some great skill for the goals.
"It is a wonderful result for us but if we don't follow it up it is a waste so we are not going to get too excited about it."
