Pompey’s unbeaten home record will face another stern test when they face Wycombe on Boxing Day.
But Kenny Jackett’s side are the 5/6 favourites with Sky Bet to secure another three-point haul at Fratton Park.
It finished 2-2 when the sides met on the south coast last season and you can find odds of 14/1 on a repeat of that scoreline.
The hosts kept a clean sheet when beating Ipswich on Saturday, so winning without conceding again might prove tempting at 2/1.
Alternatively, those expecting a trickier contest should take a look at Pompey battling from behind to take the points at 11/1.
The forward trio of Ellis Harrison, John Marquis and Brett Pitman are the joint 9/2 favourites to net the opener.
