Pompey will face Championship opposition when they host QPR in the fourth round of the Emirates FA Cup on Saturday.
But it is the League One side that are the 7/5 favourites with Sky Bet to secure victory after 90 minutes.
It finished 1-1 when the sides last met at Fratton Park back in 2010 and a repeat of that scenario carries odds of 5/1.
There are plenty of Request-A-Bet specials to look at, including more than 3.5 goals and seven corners for each team at 33/1.
Reckon that is too unlikely? You can back the Blues to net at least twice and win five or more corners at 5/2.
With Jamal Lowe suspended, Ronan Curtis and Brett Pitman are the joint 11/2 favourites to notch the opener.
Pompey might be favourites with the bookies on Saturday, but they are 80/1 outsiders to lift the FA Cup at Wembley in May.
