Millwall currently find themselves in choppy waters after slipping back into the Championship relegation zone.

Having moved out of the bottom three with a win against Aston Villa, they were cast back into the dreaded drop zone after a 3-1 defeat against Reading last Saturday.

The Lions dominated proceedings but were nowhere near clinical enough to convert more than one of their 23 attempts on goal.

Reading had that cutting edge, meanwhile, managing three strikes to sink the Lions.

Millwall have won just twice this season in 13 matches and have lost four of their last six games.

It is a concerning run of form from the London club who will be hoping two home fixtures this week will give them the edge as they look to get back to winning ways after Saturday’s disappointing results.

With that said, here are two things Harris must do to change Millwall’s fortunes.

Neil Harris all too often leaves it too late to bring players on to affect a match - the majority of his subs are in the last 15 minutes.

If you want a player to be able to get up to the speed of the game, bring them on earlier, especially when the Lions have been trailing for much of the season.

If Millwall want to improve, Harris needs to make the right subs at better times.

Instead of the wrong subs at the wrong times.

It’s something that has been an issue all season and needs to be remedied, and fast.

When Millwall are chasing a game, Neil Harris opts to change to a 3-4-3 formation to find a way back into the game.

Why not start like this?

Byron Webster and Shaun Hutchinson are both fit again, and could easily play with Jake Cooper at the back.

Have Mahlon Romeo and Shane Ferguson or James Meredith as wing-backs and have a trio in their attack.

Tom Bradshaw looks lively when he gets his customary five minutes per match and might benefit having Steve Morison and Lee Gregory up there with him.

Morison would be the target, Gregory the workhorse and Bradshaw could be the nippy poacher to give Harris more options in attack.

It would be progression and something worth looking at if Harris is to change Millwall’s fortunes.
