The Blues have made an unsatisfactory start to the campaign, collecting just two points from their opening three games.
Calls for Kenny Jackett to be sacked by fans have increased and the boss knows he must deliver at the Pirelli Stadium.
Following last weekend’s insipid 2-1 loss to Wigan, Jackett may look to make changes to his starting XI against the Brewers.
Here’s a look at how Pompey could line-up...
5. Centre-back - Lee Brown
Not the most popular among fans but Pompey need leaders and experience at this time. Brown's a big character who provides that. Photo: Joe Pepler
6. Holding midfield - Tom Naylor
While there have been some concerns surrounding the engine room, the skipper is the established member of Pompey's starting XI. Photo: Joe Pepler
7. Holding midfield - Andy Cannon
Bryn Morris has struggled early this season, with Pompey in the market for a new recruit. In the meantime, added energy, fizz and someone who can drive with the ball is needed. That's what Cannon brings, although Ben Close is another candidate. Photo: Joe Pepler
8. Right wing - Marcus Harness
Was one of Pompey's brighest players against Wigan and was a shock when he was substituted. Heading back to his former club for the first time and may feel he has a point to prove. Photo: Joe Pepler
