Pompey will look to put their first league loss of the season behind them when they visit Crawley in the Checkatrade Trophy on Tuesday evening.
And Kenny Jackett’s side are the 3/4 favourites with Sky Bet to collect all three points from the group stage encounter.
The hosts – who currently sit just outside the League Two play-off spots – can be backed at 14/5, with the draw at 5/2.
Pompey triumphed 3-1 when the sides met in last season’s competition and a repeat of that scenario carries odds of 11/1.
Punters can also put their money on a 1-0 victory for the Blues at 6/1 or a more resounding 4-0 win at 25/1.
Those anticipating a comfortable evening in Sussex might be tempted by the visitors leading at the interval and the final whistle at 7/4.
Jackett could decide to make changes to his side, so Oli Hawkins to net the opener at 5/1 looks a decent option.
Elsewhere in the first goalscorer market, Joe Mason, Ben Thompson and Christian Burgess are available at 11/2, 18/1 and 40/1 respectively.
And you can even tip Pompey to go all the way and hold the trophy aloft at Wembley in March at 16/1.
