LAST MEETING: Leyton Orient 0 Millwall 0 (League One 06-12-2008)

LAST TIME AT THE NEW DEN: Millwall 0 Leyton Orient 1 (League One 15-03-2008)

HEAD TO HEAD: Leyton Orient 19 wins, Millwall 25 wins, and 20 draws.

FORM: Millwall are challenging for promotion, but struggling for consistency, in fourth place. The Lions lost to mid-table Bristol Rovers at the weekend, after they had beaten second-place Peterborough United.

DANGER MAN: Ex-Orient striker Gary Alexander is top scorer with a grand total of nine league goals. But a red card at Bristol means the striker will miss the game. On-loan striker Jason Price is one to watch in attack, which features two wingers in Dave Martin and James Henry, who both can cause problems.

FUN FACT: Millwall have had just one spell in England's top tier, between 1988 and 1990.

PREDICTION: Millwall 1 Leyton Orient 2.
