After leaving his post at Crystal Palace earlier in the season and making the short move across south London to Millwall, Ian Holloway faces the most important game of his Millwall managerial career so far. The rivalry between the Lions and the Addicks hasn't grabbed headlines over the years in the same way that clashes with West Ham have, but the outcome will still matter dearly to the fans.
To find the last time Charlton beat Millwall, you have to go back to 1996 in a season where they managed the double over their rivals. Now in Jose Riga's second game in charge, he has a chance to change that.
Charlton's defence looked solid in mid-week against Huddersfield, and with Holloway's men finding the net just four times in eight games, Charlton will be hoping for a clean sheet – something they haven't achieved away from home in 10 games. Dorian Dervite has been key in defence for the Addicks all season and will be hoping to help them achieve that. Millwall striker DJ Campbell will be unavailable for the game, but new signing and former Wolves front-man Stefan Maierhofer could be set for a debut.
The importance of this game eclipses bragging rights, with Charlton sitting bottom of the Championship. But with four games in hand, three points on Saturday would take them above Millwall. Charlton's fate really is in their own hands as they look to avoid relegation into League One.
Both of these sides have struggled to find the back of the net consistently this season, and so Saturday could be a nervy affair with a draw not suiting either of them. The south London derby is set to attract Millwall's biggest crowd of the season, who will no doubt play their part in spurring the team forward. The result of this one can certainly help build momentum for the winners, defeat is not worth thinking about.
