Neil Harris’ side exacted revenge for the 3-1 league defeat to their FA Cup visitors Southend as Millwall snatched victory 1-0.

Only one point separates the two sides in League One and the contest was evenly matched throughout.

A game of few clear-cut chances was characterised by spirited defence and a more open approach from both teams late-on paid dividends for Millwall with Mahlon Romeo’s effort enough for his side to progress.
