Millwall are facing a tough test for the remainder of the season, with the Lions looking like they could be in relegation dogfight. 

Neil Harris' side are currently sat 20th in the Championship table and are just five points from safety, which will be concerning reading for Millwall supporters.

It's sure to be an interesting transfer window for the Millwall boss, who certainly needs to make additions to his current playing squad to help aid their fight against relegation.

They have already signed Derby defender, Alex Pearce on loan until the end of the season, and he'll be hoping to make a positive impact at The Den.

There are also a number of players that are struggling for game time at the club this season, and Harris could be tempted to offload some of those players in this month's transfer window.

But who should be pushing for a transfer away from Millwall this month?

Find out below.....

Jiri Skalak

The former Czech Republic international only arrived at Millwall in the summer from Brighton, but has struggled to make a positive impact on the relegation threatened side.

Skalak has made just five starts in all competitions and could benefit from a loan spell away from The Den to find regular playing time.

David Martin

The 32-year-old moved to Millwall in 2017, but has only made four appearances in total which will be hugely disappointing for the shot-stopper.

He is behind both Jordan Archer and Ben Amos in the pecking order and surely be should be one of the first players eyeing a move away from the club this month in search of regular game time.

Sid Nelson 

The centre-back is currently on loan with Swindon Town in League Two, and is unlikely to ever force his way back into the Millwall starting XI anytime soon.

With the arrival of Alex Pearce, it's unlikely that the 23-year-old is going to feature for Harris' side in the near future, and a permanent move away from the Championship side could be the best move for both parties.
