Rotherham manager Ronnie Moore lamented his side's defending in the 5-2 Johnstone's Paint Trophy defeat at home to Huddersfield.
The Millers were taken to the cleaners by a rampant Terriers side and found themselves a goal down inside the first minute, with goals from Ryan Taylor and Ryan Cresswell proving brief respite.
Moore said: "It was going to be tough, we knew that.
"I was pleased with the way we got back into the game and we had a great chance to make it 2-1. It`s all about things going for you at the right time, but we were playing a quality side.
"But it doesn't matter if you are playing the Dog and Duck, if you defend the way we defended you are going to have problems. We were just found wanting at times in our defending.
"But we'll be in morning and afternoon, working on that ready for Saturday."
