Dave Jones says that everyone in the dressing room must stick together and show more gumption if the Owls are to escape from the lower regions of the Championship.
Wednesday went down 2-1 at home to Huddersfield on Saturday and the manager acceded to the fact the performance was lacking.
But Jones insists himself, his staff and players will bounce back and get the season back on track.
He said: “It was a poor performance. The frustrating thing is that we were so good against Reading last time here and then we go to that.
“It’s up to everyone to turn this around, and that starts from the staff and through to all the players. We have all got to stand up and be counted.
“The first goal might have been offside but it doesn’t matter because we didn’t do our jobs properly.
“We have people in pockets there and someone came out, which gave them the chance to take advantage and they did that.
“I know these players can play at Hillsborough because they did it so well in the last game. But is there a mental block sometimes? If there is, we have to unlock it.”
Jones also explained his thinking in making four changes to the team that lost at Derby last time out.
Joe Mattock, Jose Semedo, Miguel Llera and Damian Martinez all started against the Terriers– with the goalkeeper change proving the biggest talking point.
He explained: “I made changes because we didn’t play well in the last game. No manager drops a player for playing well.
“With Chris, we hadn’t kept a clean sheet and I don’t think he was playing to the standards he sets himself.
“Damian came in and in all honesty didn’t have a lot to do and didn’t do anything wrong.
“If I have to make changes all over then I will because we have to start winning games and that is the bottom line.”
