Following Tuesday night’s narrow cup defeat at Cardiff, it is back to League One action for Pompey this weekend.
They make the relatively short trip to Oxford and it is the hosts who are 6/4 favourites with Sky Bet to claim all three points.
Both sides won on the opening day and Kenny Jackett’s men can be backed at 19/10, with the draw at 11/5.
A 1-0 Blues victory – which they recorded at the Kassam Stadium in 2014 – is priced at 7/1, with a 2-1 triumph at 9/1.
But if you do not think it will be that simple, take a look at the 16/1 on offer for Pompey coming from behind to secure the win.
Skipper Brett Pitman is the 11/2 favourite to net the opener and 9/1 to repeat his Rochdale heroics by bagging a brace.
Elsewhere in the first goalscorer market, Conor Chaplin, Gareth Evans and Christian Burgess are available at 13/2, 9/1 and 25/1 respectively.
