Pompey return to League One action this weekend with a trip north to face a fellow promotion-chasing side in Fleetwood.
And Sky Bet cannot separate the sides, with both able to be backed at 13/8 to claim all three points at Highbury.
The hosts are just two points Kenny Jackett’s sixth-placed side, so the draw could be a tempting option at 21/10.
It finished 2-1 to the Blues at the same location in last month’s FA Cup tie and a repeat of that scenario carries odds of 9/1.
They came from behind to secure passage to Wembley earlier in the week and it is priced 16/1 for them to turn a deficit into success on the Fylde coast.
Or you could select both Harrison and Curtis to find the net at 10/1, with Marquis and Curtis the same price.
Please gamble responsibly and remember that all odds are subject to change. When the fun stops, stop.
