Millwall have had a poor start to the season, winning just once in their opening seven matches.

Three draws and three defeats make up the rest of the Lions’ results in this year's iteration of the Championship to date, ahead of a London derby on Wednesday evening.

Capitan Steve Morison has started six of Millwall’s seven matches, coming off the bench once in the 1-0 defeat to Rotherham United last month.

Besides the Derby County performance, his recent form has been questionable, and there have been calls from the Den faithful to drop the former Wales international.

Neil Harris will have a selection dilemma should he choose to drop the striker.

The 35-year-old has failed to score so far this campaign, and in fact, has not scored since April in the 1-1 draw with Sheffield United last year.

With that in mind, here are two clear reasons why Harris must axe Morison from Millwall XI.

Morison is adept at winning the long ball and getting it down for his teammates to win the second ball and try to create a chance on goal.

This season that has not worked so well with opponents knowing how a Neil Harris team is going to play and nullifying the threat, rendering Steve Morison semi-obsolete during games.

He hasn’t won as many headers this year as he did last, and that is a big part of Millwall’s game and if that doesn’t work there isn’t another way of playing.

A second season in the Championship means clubs at this level will understand how teams new to the division play and formulate a plan to defeat them after falling foul of their tactics the year before.

With Millwall, they have one way of playing, in the post part of a game.

Invariably, Jake Cooper will loft a long pass to Steve Morison to head down for the Lions to win the knock on.

If teams know how they play, they will combat it. It is working this season with only one win registered.

Dropping Morison will allow Millwall to alter their style of play and give them another option, with the knowledge that the striker in on the bench if needed.

Keeping him in the side alerts opponents of how the Lions will set up and it has become predictable.
