Neil Warnock was frustrated with his side's mistakes in Tuesday's 3-1 defeat to Bristol City.
“We’re up here one minute and down here the next,” he said.
"There were a lot of disappointments tonight. I praised the front line on Saturday but I thought they were non-existent tonight.
"You can say is it a game too many, but I don’t think so. We made mistakes and ended up chasing the game.
"I said at half-time I want us to win the second half, and I thought if we’d got a goal earlier they would have been trembling a bit."
