Pompey will try to close the gap on the automatic promotion places when they host Scunthorpe this weekend.
And Kenny Jackett’s side are the 8/13 favourites with Sky Bet to secure all three points at Fratton Park.
The visitors – who could still be drawn into a survival battle – can be backed at 17/4, with the draw at 11/4.
It finished 5-1 when the Blues last played on home soil and a repeat of that scenario carries odds of 66/1.
A more realistic selection to tempt punters, however, could be a 1-0 success at 11/2 or a 2-1 triumph at 15/2.
You can also take advantage of a Sky Bet boost, with Pompey coming out on top in a contest where both sides find the target moving from 5/2 to 3/1.
Those who want to predict the number of corners should take a look at there being nine or more at 2/5 or at least 12 at 7/4.
The Blues are due a clean sheet – having not kept one in their past three league contests – and you can select them to win without conceding at 13/8.
Omar Bogle, Oli Hawkins, Jamal Lowe and Brett Pitman are the joint 4/1 favourites to net the opener on Saturday.
Elsewhere in the first goalscorer market, Viv Solomon-Otabor, Ben Close and Christian Burgess are available at 6/1, 12/1 and 50/1 respectively.
