Barnsley boss Mark Robins is already planning changes to his side after their "worst possible start" to the season.
The Tykes, who were thrashed 4-0 by QPR on the opening day, crashed out of the Carling Cup 1-0 to Rochdale courtesy of Anthony Elding's header.
Robins said: "There was no tempo to the game especially in the final third and there was no cutting edge. We got caught between two stools. Something needs to be done."
He added: "Their goal was a soft goal, it was just a long ball forward and they got between us. Then we didn't have the impetus we needed to win the game. We could have played until midnight and we still wouldn't have scored.
"We've got a lot of hard work to do on Thursday and Friday before our next game, on how we attack teams. We have got to be strong and win the game on Saturday.
"It's been the worst possible start to the season we could have had and the only ones who can change that is ourselves. We have got to learn."
