Pompey put their promotion push to one side this weekend, as focus switches to trying to reach the third round of the Emirates FA Cup.
And Kenny Jackett’s side are the 23/20 favourites with Sky Bet to win at fellow League One side Rochdale on Sunday.
The hosts – who have already been beaten once by the Blues this season – can be backed at 11/5, with the draw at 5/2.
Pompey triumphed 3-1 at Spotland back in September and a repeat of that scoreline carries odds of 16/1.
Fans might prefer to take a punt on a narrower 1-0 win at 8/1 or even a more emphatic 4-0 success at 50/1.
Or you could hedge your bets by looking at either a 1-0, 2-0 or 2-1 victory at 9/4, or 3-0, 3-1 or 3-2 at 6/1.
And if you suspect the magic of the cup will be at its strongest, then take a look at the Blues battling from behind at the break before progressing at 25/1.
Ronan Curtis, Oli Hawkins and Jamal Lowe and Brett Pitman are all the joint 11/2 favourites to net the opener.
Elsewhere in the first goalscorer market, Gareth Evans, Tom Naylor and Matt Clarke are available at 15/2, 22/1 and 28/1 respectively.
The real optimists among you, of course, might want to place a cheeky bet on Pompey going all the way and lifting the trophy for a third time at 500/1.
