League One Millwall capped a significant week in their existence with a 1-0 home victory over Watford that took them into the fifth round of the FA Cup.
Another convincing performance was finally rewarded with the goal it deserved when Steve Morison's late, close-range finish ensured Watford became the second Premier League team the hosts have eliminated this season.
It also concluded the week in which their future at The Den became secure after Lewisham council's abandonment of a controversial property scheme.
Watford manager Walter Mazzarri had retained only four players from the team that last week drew 2-2 at Bournemouth in the Premier League, having spoken of his wariness of their schedule of three games in six days, but his gamble undermined them.
