Millwall only missed out on automatic promotion form the Championship by a couple of points last season and Portsmouth played a huge part in that Lions near miss.
Pompey did the double over the Londoners last term, winning 3-1 in both meetings, two results that stopped the capital side's promotion charge in its tracks.
The Lions would love to avenge those reverses, yet they head down the A3 muddling along in mid-division, one place above Portsmouth and only on goals scored.

Best Bet: Draw @ 9/4
The Championship league table says there is nothing between these two sides after 11 rounds of action and that may be the case over 90 minutes on Saturday as well.
Portsmouth have drawn three of their last six culminating in Tuesday night's excellent 1-1 draw at Wolves.
Millwall have drawn three of their last five - all by 2-2 scorelines - but were kicking themselves at the last of those at home to Lincoln City, a match they were odds-on to win.
Alternative Bet: Over 4.5 cards @ 11/10
Millwall's failure to beat Lincoln last weekend wasn't the only talking point from The Den.
Just as eye-catching were the 11 cards shown by referee Reuben Ricardo, 10 yellows and a red for Lincoln's Deji Elewere.
Millwall's 11 games this season have produced 54 cards, Pompey's 11 have racked up 45 and, given that these sides are physical and spiky, expect over 4.5 cards.
