MATCH PREVIEWHaving made a great start to the season, both these teams are looking to address alarming slumps in their form. Cardiff have lost their last two matches, while Millwall, who went out of the Carling Cup in midweek, were hammered 6-1 at home by Watford last Saturday.
That mauling was the biggest defeat suffered by a Championship side this season, and Millwall are without a win in their last three matches. This is a test of the south London side's mettle, and boss Kenny Jackett will be hoping for a strong response.
Despite their recent wobble, the Welsh club are third in the table and remain formidable opponents on their own patch. They are unbeaten in 10 home matches since their last defeat at the Cardiff City Stadium, against Barnsley in February.
Cardiff, who have not beaten Millwall in the league for 27 years, also boast the second best defensive record in the division. Only leaders Queens Park Rangers have conceded fewer league goals than the Bluebirds, who have let in just six.
• These clubs have met 50 times in the league. Millwall have won 17 of those matches and Cardiff 16, with 17 draws. Five of the last eight have been drawn.
• A defeat would mean three consecutive losses for Cardiff for the first time since November last year.
• They are three goals away from the club's 3,000th at home in their league history.
• Cardiff have the best disciplinary record in the Championship, having picked up only four yellow cards this season. They have also committed fewer fouls than any other side in the division (51).
• If selected, Jay Boothroyd will be making his 100th appearance for the club.
• Millwall have conceded five goals in the final 15 minutes of Championship game this term. No team have shipped more.
• Lions boss Kenny Jackett has fielded 17 players in second-tier matches this season. Only his former club Watford have used fewer.
• Goalkeeper David Forde, a former Cardiff player, is set to make his 100th appearance for Millwall.
