Pompey will look to put their first League One points on the board when they host Tranmere on Saturday.
And Kenny Jackett’s side are the 8/13 favourites with Sky Bet to secure victory at a packed Fratton Park.
Pompey triumphed 3-2 when the sides last faced off four years ago and a repeat of that scoreline carries odds of 28/1.
The Blues battling back from an interval deficit to emerge on top – which happened in that last meeting – is also priced at 25/1.
But the bookies instead believe that the hosts will win both halves, which has the shortest odds of 11/8.
And those taking a longer view might be interested to see that the Blues are the joint 15/8 second favourites to secure promotion.
