Millwall made it a perfect week by following up their away win at Hull with a narrow 1-0 home victory over Derby County at The Den on Tuesday night. A solitary goal was enough to separate the sides in a hard-fought Championship battle, moving Millwall further up the table. The only goal of the game came in the first half, with Millwall's forward reacting quickest to a loose ball in the box to poke home from close range. Derby responded with pressure in the second half, forcing the Millwall goalkeeper into a couple of important saves, but they could not find an equalizer. The match was a physical contest with numerous fouls, and Derby's frustration boiled over late on when they had a player sent off for a second bookable offense. This result completed a double over Derby for Millwall this season and continued their impressive form, while it halted Derby's momentum from their previous win. The Millwall manager praised his team's defensive resilience, while the Derby boss felt his side deserved at least a point for their efforts.
