Pompey have lost their past four games in all competitions and haven’t won in the league since Shrewsbury’s visit to Fratton Park on August 17.
The head coach made five changes to his side for the 2-1 defeat at the hands of Cambridge United on Saturday.
And he’ll be tempted to make more, along with a formation change, as he looks to get Pompey out of their current rut which also includes one goal in four League One outings.
The system switch could see him look to use wing-backs, making the most of the impressive Mahlon Romeo’s skills set, and go head-to-head with Plymouth boss Ryan Lowe’s preferred way of playing.
But what does that mean in terms of the starting XI?
Well, it could mean the likes of Marcus Harness, Ellis Harrison and Shaun Williams miss out, while Kieron Freeman, John Marquis and Louis Thompson are handed starts.
Here’s an example of how Pompey in a 3-5-2 system for tonight’s game could look.
9. Left wing-back - Lee Brown
We all know the defender loves getting forward - and we all know he's capable of scoring goals. Pompey do need to try something different to get the goals flowing again - and Brown operating at left-wing back could be a solution.
10. Centre- forward - John Marquis
Marquis, with only one goal in eight appearances this season, was left out of the starting line-up for the visit of Cambridge. Yet Danny Cowley has already stated that his decision to do so was a mistake. Expect Marquis to be handed a recall tonight. Hopefully, his recent omission can kick-start a run of form we all want from the forward.
11. Centre-forward - Ronan Curtis
A change of role for the winger - but a position Curtis loves playing in. Playing with wing-backs means he'll be required to tuck in and help Marquis up top, which will no doubt keep the Pilgrims' central defenders on their toes. Saturday's goal will have given Curtis some much needed confidence, which his fellow forwards can lean on and make the most of. Cowley could stick with Ellis Harrison and play him up top with Marquis, but evidence suggests it's not a partnership that works.
