The Lions last victory against the Gills came in the Quarter Finals of the Auto Windscreen Shield when a Richard Sadlier 'Golden Goal' continued their run in the competition which was to end with a visit to Wembley.
There will be no Sads in the Millwall squad this time following his retirement this week, but with Bob Peeters, Neil Harris and Noel Whelan all vying for the two striking slots, Mark McGhee has the enough options to try and secure victory.
Both David Livermore and Paul Robinson are back in the squad after injury and tomorrow's game should see the debut of former Juventus winger Abou, who has been impressing in training all week.
Gillingham meanwhile have an enforced change between the sticks with Jason Brown away on International duty with Wales. Rod Wallace should return to the squad but Tommy Johnson is suspended.
Millwall squad from: Warner, Gueret, Muscat, Lawrence, Ryan, Craig, Nethercott, Ward, Robinson, Ifill, Roberts, Wise, Livermore, Cahill, Juan, Hearn, Peeters, Whelan, Harris, Abou.
