Neil Harris have less than three weeks to add his Millwall squad to try and replicate the form his side displayed in the second half of last season.

The Lions went on an incredible run of form that saw them narrowly miss out on the play-offs and Harris has said he will be active during January to freshen up his team.

Having struggled to hit the heights of the final few months of the 2017/18 campaign, the Lions are in need of new additions to improve their side and to also add to their forward line that has Tom Elliott and Tom Bradshaw missing, with the latter out for the season with a knee injury.

If Millwall are to emulate their sequence of 12 months ago, then new faces are a necessity, and inside the next 17 days, there is plenty of work that needs to be done to get potential deals over the line.

With that said, here’s the transfer business that Harris and the Lions need to get done before the end of the window.

Jiri Skalak to depart for regular game time

It is safe to say his time at Millwall has not gone according to plan, starting just four times since his summer move from Brighton and Hove Albion.

Nine substitute appearances has been where most of his game time has come from, registering just one assist in that time.

With Fred Onyedinma being recalled from his loan spell at Wycombe Wanderers, Skalak’s place in the side could come under more of a threat.

And if he does fall down the pecking order, a loan move away could help his confidence to get regular first-team football.

Ben Marshall to make a triumphant return

And if Skalak did leave the club this window until the end of the season, then that opens up a place in the side for the return of a former player to The Den.

Ben Marshall was at The Den last weekend watching his former sides face one another when Blackburn travelled to take on Harris’ team.

The Norwich man has made just four appearances for his parent club this season and has found first-team opportunities at Carrow Road hard to come by.

And he could return to the club where his performances won him a move to Norfolk to inspire once more Millwall to the same form they achieved last year after Marshall’s arrival 12 months earlier.
