Pompey return to league action this weekend with a trip to face promotion-chasing Peterborough.
But Kenny Jackett’s side are the 2/1 underdogs with Sky Bet to collect all three points at London Road.
The hosts – who are five places, but just three points, behind in the table – can be backed at 6/5, with the draw at 12/5.
Pompey won 2-1 in last season’s corresponding fixture and a repeat of that scoreline carries odds of 10/1.
Punters might instead prefer to put their money on a 1-0 victory at 16/1 or even a convincing 4-1 success at 66/1.
You can also take advantage of a Sky Bet boost, with the Blues coming out on top in a contest where both sides find the target moving from 3/1 to 7/2.
Posh are the division’s highest scorers, so both teams hitting the net and the game containing more than 4.5 goals might be tempting at 9/2.
Or if you are expecting a comfortable afternoon for Jackett’s men then they are on offer at 5/1 to win without conceding.
Ronan Curtis is the 11/2 favourite to net the opener, ahead of strikers Ellis Harrison and John Marquis at 6/1.
Elsewhere in the first goalscorer market, Ryan Williams, Tom Naylor and James Bolton are available at 11/1, 22/1 and 40/1 respectively.
