Pompey will search for a return to winning ways when they host Peterborough in the Checkatrade Trophy on Tuesday.
And Kenny Jackett’s side are the 23/20 favourites with Sky Bet to secure their spot in the last four of the competition.
The visitors – who currently sit sixth in the League One standings – can be backed at 2/1, with the draw at 23/10.
Pompey won 2-1 when the sides met earlier in the season and a repeat of that scenario carries odds of 7/1.
Punters might instead prefer to put their money on a 1-0 victory at 15/2 or even an emphatic 4-0 success at 33/1.
A popular Request-A-Bet is for the hosts to triumph, with both sides hitting the target, while also gaining at least four corners and 20 booking points at 25/1.
Those who think the contest will go the distance can take a look at either side winning on penalties at 11/2.
And if you reckon the Blues will have to work hard for their progress, then you can get odds of 10/1 on them coming from behind to emerge victorious.
The hosts are likely to make several changes for the quarter-final tie, so the usual favourites in the first goalscorer market might be best avoided.
Brett Pitman is the 11/2 favourite to net the opener, while Louis Dennis, Dion Donohue and Christian Burgess are available at 13/2, 25/1 and 40/1 respectively.
With eight teams now remaining in the competition, the Blues are on offer at 11/4 to win the whole thing.
