AFC Wimbledon sit rock bottom and seven points adrift of safety with only 14 matches remaining in the third tier despite winning at Walsall in midweek.
But such a dismal league performance has done little to quell their appetite for a cup shock.
Under the guidance of Crazy Grange alumnus Wally Downes, the Dons stunned Joey Barton’s Fleetwood in a five-goal
thriller thanks to a 90th-minute winner from Kwesi Appiah before going 3-0 up in just 46 minutes at home to West Ham.
They then held off a spirited Hammers fightback to claim a famous 4-2 victory.
Opponents Millwall will be glancing nervously over their shoulders in the Championship relegation battle and currently hover just three points above the drop zone, albeit with a game in hand on their rivals.
They saw off Hull in round three before a controversial and highly dramatic 3-2 defeat of Premier League Everton.
AFC Wimbledon will be without Steve Seddon, Kwesi Appiah and James Hanson at home to Millwall in the FA Cup on Saturday.
On-loan left-back Seddon, who scored the Dons’ winner in the league against Walsall on Saturday, cannot play in the competition as he is cup-tied.
The fifth-round tie with the Lions comes too soon for Appiah, who is still struggling with a hamstring injury he suffered in a 2-0 defeat to Burton on February 9.
Fellow striker Hanson is back in training after a groin problem, but he, too, will not be ready in time.
