THE Reds were crushed 5-1 at home to Watford on Saturday.
Barnsley's poor defensive record continued and are now second bottom, with just four points from eight games.
The match began frantically with three goals in the first 17 minutes as Troy Deeney fired the Hornets ahead, before Jason Scotland got his first goal of the season. It wasn't level for long though as Davide Faraoni tapped home a deflected cross by Lewis McGugan to restore Watford's advantage.
The fourth goal was always going to be crucial and Watford got it just before half-time when Deeney played Ikechi Anya in down the left of the box and he powered past Wiseman before setting up Fernando Forestieri to make it 3-1.
Barnsley were better in the first half and Manuel Almunia had to make a phenomenal one-handed save to deny Martin Cranie's header from four yards out.
However, Sean Murray finished the Reds off when he fired into the bottom left corner with an excellent 25-yard strike.
Anya then made it five on 79 minutes when he tackled David Perkins on the edge of the Watford box following a Barnsley corner and sprinted the length of the pitch before firing in.
"We've been below our standards and against a Watford team you can't even get away with 10 per cent off," said David Flitcroft. "Some players were 30 or 40 per cent off the standards they've set.
"They've let the group down and they've certainly let the fans down. I want to design a football team that wins games. It's something I'm obsessed with and, at the minute, we're not doing that."
