Pompey have yet to record successive victories this season.
But they are tipped to do just that by Sky Bet, who make Kenny Jackett’s side 1/2 favourites to beat Oldham this weekend.
The visitors – who recently dismissed John Sheridan as manager – can be backed at 11/2, with the draw at 16/5.
You can place a group bet on the hosts winning by either a 1-0, 2-0 or 2-1 scoreline at 13/8, while a 4-0 victory carries odds of 18/1.
And a punt on the game being all square at the break before Pompey eventually triumph is priced at 3/1.
The prolific Brett Pitman is – once again – the 3/1 favourite to net the opener, ahead of Oliver Hawkins at 9/2.
Elsewhere in the first goalscorer market, Jamal Lowe, Stuart O’Keefe and Christian Burgess are available at 13/2, 22/1 and 33/1 respectively.
