Doncaster Rovers manager Sean O'Driscoll accepted that his side had produced their worst performance of the season in the 3-0 defeat at Cardiff City.
O'Driscoll has seen his team put together an amazing run of results in recent weeks, but had no complaints after a comprehensive loss in South Wales.
He told the Sheffield Star: "We didn't start well. Our backline couldn't cope with Jay Bothroyd and Michael Chopra and our frontline couldn't cope with Roger Johnson and Gabor Gyepes, so that gave us problems in midfield.
"Once we got over the first ten minutes and went a goal down, I thought that there was a period of the game when we controlled it a little bit, but the second goal killed it.
"I don't think that anybody who was 2-0 down at half-time at Cardiff would expect to come back and win the game.
"We've got beaten before, but on a lot of those occasions people have said how well we've played, but we just didn't turn up today.
"We didn't see it coming. Sometimes you have an inkling in the week in training, but that wasn't the case."
