Find out the facts and figures ahead of Tuesday's gameMillwall and Gillingham lock horns for the 97th time at The Den on Tuesday night in the latest round of Checkatrade Trophy fixtures.
Of the previous 96 encounters it is The Lions who hold the head-to-head advantage with 48 wins compared to 27 for the Kent side, while 21 have ended in draws. All but eight of the games between the two clubs have been in regular League action.
The most recent meeting came in May of this year on the last regular day of the 2015/16 season, when Lee Gregory scored a 98th-minute winner from the penalty spot in dramatic scenes at Priestfield. Aiden O'Brien had given The Lions an early second-half lead but a red card to Mahlon Romeo in the closing stages handed Gillingham the initiative and they looked to have secured a draw when John Egan struck two minutes into injury-time. That proved not to be the case, however, as Gregory lashed home from 12 yards to send provoke joyous scenes in the away end.
Gillingham's last visit to The Den was an entirely more memorable affair for Justin Edinburgh's side, though, when goals from Dominic Samuel (2) and Bradley Dack (penalty) secured a comfortable 3-0 victory over 10-man Millwall, who had Jordan Archer sent off after 25 minutes in SE16. That was a first victory at The Den for The Gills in six attempts dating back to December 2003.
Both clubs head into Tuesday's fixture on a poor run of form, with Millwall winless in six and Gillingham having enjoyed just one victory from their last eight games. In the previous round of Checkatrade Trophy games The Lions beat West Bromwich Albion 2-0 while The Gills lost 2-1 away to Luton Town, putting extra pressure on them to get a result at The Den if they are to progress from Southern Section Group H.
