Gary Rowett is preparing for his third match in charge of Millwall, as his side contest the South London derby against Charlton Athletic this Saturday at The Den.

In the 43-year-old's two matches in charge of the Lions so far, Millwall have amassed three points - a win against Stoke, and a defeat against Reading last time out.

However, for derby games, form often goes out of the window because of the ferocity involved.

The manager has now had enough time to analyse the players he has at his disposal, and after the disappointing performance away to Reading, Rowett may change his settled starting XI.

We look at two players who could be looking over their shoulder ahead of the big match between the South East London rivals this Saturday...

Shane Ferguson

The Northern Ireland international has featured twelve times in the Championship so far this season for Millwall, starting six games and coming off the bench for the remaining six.

Despite recently nailing down a starting spot in the Millwall side, Ferguson was substituted off at half-time for Jon Dadi Bodvarsson, which could be a sign of things to come as the latter provided an assist for Wallace's goal.

Offensively, Ferguson has not offered much so far this season. According to WhoScored, he has provided a sole assist, and averages 0.3 dribbles per game.

Ben Thompson

The attacking midfielder is often deployed behind Tom Bradshaw in a 4-4-1-1 formation, but has failed to provide the creativity that his side need this season.

Thompson has provided just one assist in fifteen Championship games, with an average of 0.5 key passes per game.

It says a lot that two forwards at the club currently have the equal highest number of assists; Matt Smith and Jon Dadi Bodvarsson with two each.

Replacing Thompson could mean reverting back to a 4-4-2 formation for Rowett, with two strikers.
