The Lions kicked off the final month of 2016 with a Cup double - after brushing aside non-League Braintree Town 5-2 in the Emirates FA Cup, they were to then exit the Checkatrade Trophy at the hands of Wycombe Wanderers.
Harry Smith scored a hat-trick in the rout of The Iron - a feat that secured his place in the record books in scoring on his League, Cup and Football League Trophy debuts.
Despite having 57% of the possession, 17 shots on goal and 13 corners, Millwall suffered a narrow defeat to Shrewsbury Town on 10th December and followed that up with a 3-0 loss at seemingly promotion-bound Scunthorpe United a week later, however, a raucous pre-Christmas atmosphere at The Den saw The Lions start a magnificent unbeaten run with a 3-1 success over Charlton Athletic.
Lee Gregory's double handed supporters a late Christmas present in the Boxing Day win over Swindon Town, whilst the striker was on target once more - along with Fred Onyedinma - in a 2-1 win over Gillingham to round off the year.
2017 began with a pulsating London derby draw with AFC Wimbledon. Aiden O'Brien's long-range stunner and Steve Morison's delicate lob gave The Lions the lead on two separate occasions, but Lyle Taylor and now Millwall striker Tom Elliott netted to secure a share of the spoils.
Next up was the visit of Premier League side AFC Bournemouth in the third round of The Emirates FA Cup and in spite on over £40m of Cherries talent gracing the Den pitch, a superb Lions performance saw them swept aside courtesy of goals from Morison, Shaun Cummings and Shane Ferguson.
Two hard-fought draws on the road at Charlton and Bradford City followed, before The Lions rounded off January with a televised victory over another Premier League side - this time Watford - in Round Four of the Cup due to Morison's late winner.
