The team head to Highfield Road for the televised encounter aiming to banish memories of the three previous games where ten goals have been conceded.
"Definitely, we've got to draw a line under the start of the season and look to start afresh on Wednesday," considered Dean.
"It will be a tough game, especially going up there, and confidence recently has been a bit low. We've got to pull together - players, staff and supporters - and all try and turn the corner."
The ship is currently being steered by David Pleat and Chris Hughton following the departure of Glenn Hoddle on Monday and Dean hopes that the widespread trend of a positive result following a change at the top continues.
"It is common when changes are made at clubs that things seem to turn around. I don't know why that it, but I suppose that is the case."
Dean Richards says the team must 'draw a line under the start to the season' and seek to start afresh against Coventry in the Carling Cup on Wednesday.
