The Saints have seen their points cushion at the top of the league disappear in recent weeks and now sit just two points ahead of third-placed Cardiff although there is the prospect of meeting Bolton in the fifth round which will act as incentive to win this game.
The home side are warm favourites at 8/11 (Coral free bets) to claim victory against a Millwall side that sit 19 places below their opponents in the Championship, with the Lions having failed to take advantage of an extra man against West Ham on Saturday.
Kenny Jackett’s team have lost nine of their fourteen games on the road this term and they only just scrambled a 1-1 draw in the original tie thanks to a late Darius Henderson equaliser, although they will be encouraged by the Saints’ current wobble and Millwall are a 9/2 chance (Paddy Power £50 free bet) to claim victory.
After all, Saints have failed to win any of their last four matches and the early season momentum is no longer in evidence, even if they have the division’s top scorer on the books. Rickie Lambert is a 4/1 chance (Betfred bookmaker) to score the opening goal of this contest, just as he did at the Den.
