Two of English football’s fallen giants go head-to-head, both desperate to get out of the third-tier.
Portsmouth kick off fifth, having drawn their last three matches, all 1-1.
Last weekend, Colby Bishop’s equaliser rescued a point for Pompey against Morecambe at Mazuma Stadium.
So, Danny Cowley’s team have actually only won one of their last eight league matches, derailing their promotion push.
Derby County meanwhile are only below their hosts on goal difference, albeit they’ve played a game more.
The Rams came from a goal down to win 3-1 at Stadium MK on Saturday; Haydon Roberts, James Collins and Nathaniel Mendez-Laing on target.
Paul Warne’s team then extended their unbeaten streak to six matches on Tuesday night, hammering Torquay 5-0 in an FA Cup replay.
Just three nights later, who will win this huge clash at Fratton Park?
