Pompey will look to stretch their winning run into double figures when they go back on the road to face Coventry this evening.
But their opponents are also enjoying a fine run of form, having not lost in the league since before Christmas.
They left it late to beat Bolton at the weekend, though, with Max Biamou grabbing a last-gasp winner.
That saw the Sky Blues climb back above Kenny Jackett’s side and into fourth spot in the League One standings.
Issues with the owners of the Ricoh Arena mean that Coventry are currently having to groundshare again – this time with Championship club Birmingham at St Andrew’s.
That ensured there was the bizarre instance of the tenants playing host to their landlords in the FA Cup last month.
The higher-ranked side eventually triumphed on penalties after a replay, although promotion was always the priority for boss Mark Robins.
There was a dramatic meeting between the clubs on the south coast back in August, as the visitors fought back to draw 3-3, despite being reduced to nine men.
But Pompey came out on top in last season’s corresponding fixture – albeit at a different ground – with Ronan Curtis’ strike enough to settle the contest.
Andy Cannon is still sidelined with the glute injury that kept him out on Saturday, although the midfielder could be fit for the weekend.
Oli Hawkins has recovered from the head injury he suffered in a recent reserve game at Exeter and is available for selection.
Bryn Morris is running outside again as he continues to step up his recovery from a long-term groin problem.
Reise Allassani, Dan Bartlett, Wesley Jobello and Jodi Jones are all missing for Coventry with serious knee injuries.
But the hosts are hopeful that Matty Godden (groin), Kyle McFadzean (groin) and Callum O’Hare (head) will be able to feature.
