All the need to know details ahead of Sunday's televised tieMillwall and Watford meet for the 101st time on Sunday as the two clubs do battle for a place in the Fifth Round of the Emirates FA Cup.
The tie, which will be televised live on BBC One (12noon kick-off), sees The Lions and The Hornets lock horns for the first time ever in the competition's history.
There has only been one cup meeting between the two since they first met back in November 1920 - after a drab 0-0 draw at Vicarage Road, goals from Bruce Murray, Jamie Moralee, Richard Huxford and Etienne Verveer handed Mick McCarthy's men a 4-3 aggregate victory in a League Cup tie.
Despite the gulf in League positions - currently standing at 39 places - it is Millwall who hold the upper hand with regards to historical victories, with 40 wins to Watford's 30.
Recent meetings, however, are firmly in the court of The Hornets, with seven successes to their name in the last ten games.
Matej Vydra and Adlene Guediora eased Watford to a 2-0 victory at The Den in April 2015, whilst The Lions will surely want to forget a 4-0 Boxing Day defeat at Vicarage Road in 2013, as well as a 6-1 home reverse in September 2010.
Shaun Batt's solitary goal proved vital to Millwall's attempts to stay in The Championship in April 2013, whilst there have also been two draws between the pair - 2-2 in April 2014 and 0-0 in November 2012.
Two of The Lions' biggest victories over Watford came in the early 2000's. On New Years' Day 2002, current manager Neil Harris returned from a period out to memorably cap a 4-1 win by scoring a wonder-goal in the final moments, whilst in 2003, Robbie Ryan netted one of his two goals in a Millwall shirt in a 4-0 rout at The Den.
Should Neil Harris' outfit claim victory on Sunday afternoon, it will be the fifth Premier League side they have dumped out of the Emirates FA Cup, following wins over Arsenal, Chelsea, Aston Villa and AFC Bournemouth.
