Millwall earned an impressive point against second-placed Derby at the Den on Tuesday evening.

Jed Wallace could have won it for Millwall late on, while Derby winger Ikechi Anya had a goal disallowed for offside.

Here are five things we learned…

Will Millwall’s bad luck with referees ever end?

The Jed Wallace red card, the missed penalty against Brentford and the spot-kick conceded at Fulham - and that’s to name just three - there have been more.

Lee Gregory was accidentally booted in the face by Curtis Davies in the box - no penalty.

Shaun Hutchinson’s strike appeared to be cleared off the line by a hand - no penalty.

It’s two more decisions that have gone against Millwall this season. Surely their luck will change soon.

Shaun Hutchinson continues to star

Hutchinson was Millwall’s man of the match. He made a vital block to deny Matej Vydra in the first-half and nothing got past him. It was a captain’s performance in the absence of Steve Morison.

Hutchinson has arguably been the Lions’ best player this season - and last night was another example of just how important he is to the club.

Millwall have kept 10 clean sheets in the Championship and that’s largely down to Hutchinson and his defensive partner Jake Cooper.

Attacking reinforcements will boost Millwall

Morison missed out through illness while Aiden O’Brien is still sidelined with an ankle injury.

It meant Neil Harris’ only attacking option from the bench was Fred Onyedinma, who gave Millwall more of a threat when he came on.

Tim Cahill needs to get fit before being considered for selection. But the Lions are set to sign Wolves winger Ben Marshall on loan today to boost their wide options.

Wallace and Shane Ferguson are the only wingers available for selection at the moment.

Cahill and Marshall will give Harris some much-needed depth in the forward positions.

Tom Elliott failed to impress on his big night

Filling in for Morison, Elliott had a golden opportunity to stake a claim for a regular starting spot.

But he didn't do enough, albeit against one of the best sides in the division.

The big striker won his headers, but his hold-up play was poor and Millwall missed the Morison-Gregory connection.

It was only his sixth league start in what’s been a stop-start season due to injury and selection, however, he’ll need to contribute more in future games.

Tim Cahill’s reception will be remembered

Cahill rejoined Millwall on Monday after a 14-year absence. He made his name at the Den and is considered a club legend.

Despite being 38 years old, his experience will be invaluable in a young Millwall dressing room, and he is likely to have an impact coming off the bench late on in games.

He was presented to supporters prior to kick-off and received a hero’s welcome.

Cahill and Millwall fans will not be forgetting that moment anytime soon.
