Peterborough manager Darren Ferguson admitted that “something has to change” after seeing his team thumped 4-0 by Blackburn Rovers on Wednesday.
It was Posh’s third successive defeat and meant they have taken just one point from their last five matches.
Nonetheless, thanks to Reading’s points deduction, they know that they can move out of the bottom three if they win on Saturday and the Royals lose to Swansea City.
Twelve of Peterborough’s 15 points this season have come at the Weston Homes Stadium, but they do have the Championship’s worst defence having conceded 38 goals; that is five more than anyone else and an average of exactly two per game.
It will therefore be an interesting matchup against Barnsley, who are the lowest scorers in the division with just 13 goals to their name.
The Tykes are deep in trouble having lost 10 of their last 11 matches, but they hope that the appointment of Poya Asbaghi can help turn their fortunes around.
