Steve Cotterill is seeking a Barnsley victory to help exorcise the demons from one of Pompey’s worst displays of the season.
The Blues suffered a dreadful 1-0 defeat at Oakwell back in November, Adam Hammill’s stunning strike separating the sides.
It is one of three performances the Blues boss regards as the worst his men have produced so far.
Defeat at Preston in the third league game of the season and the abject 2-1 loss to Burnley last month complete the trio of catastrophes.
Now the Tykes visit Fratton Park tomorrow.
Pompey are seeking a successive victory to build on last weekend’s impressive Doncaster triumph.
And Cotterill is also eyeing some Barnsley revenge.
He said: ‘We were just rubbish at Barnsley.
‘I don’t know what it was, we looked back on it and you are going to get them.
‘I can say the games we’ve had like that.
‘Preston away was another one, Burnley at home another one.
‘Those three games, I think, from start to finish we didn’t get going.
‘I suppose that’s not bad considering we have now played 30-odd games.
‘There have been games – even when we have been down to the bare bones – when we’ve at least done well in one half whereas not so well in another.
‘But I would say for 90 minutes in those three games we weren’t in it.
‘We weren’t in the game, we didn’t look like we were going to get in the game.
‘I felt the performances against those three teams were very, very lethargic for the full 90 minutes.’
Cotterill may have to take on Barnsley without Darryl Flahavan.
Jamie Ashdown’s understudy injured his ribs in training yesterday.
But David Nugent is expected to play despite not training yesterday with a tight hamstring.
Cotterill added: ‘Darryl Flahavan took a bit of a bang in the ribs yesterday morning.
‘Nuge had a little bit of a tight hamstring and didn’t train for a precaution.
‘He should be okay tomorrow.’
