Steve Morison fired Milwall into the fifth round of the FA Cup
Even if the League One Lions had been thrashed 6-0 they would still remember it fondly.
News in midweek that the land round the Den was no longer being bought up against their will had been a huge boost and meant the club wouldn’t be forced to relocate to Kent.
And a place in the FA Cup fifth round is now deservedly theirs after Morison volleyed home in the 85th minute.
Sub Shane Ferguson found the striker, now in his third spell as a Lion, at the back post to fire past Watford keeper Heurelho Gomes.
And the Lions fans can now start dreaming of a repeat of 2004 when they made it all the way to the final of this famous competition.
Watford were in the last four last season but the seven changes boss Walter Mazzarri made was a give away that they weren’t too bothered this time.

Express Sport takes a look at the top 10 FA Cup upsets of all-time
1 of 10
Non-league Sutton United had reason to celebrate in 1989 when they eliminated top flight Coventry in the third round thanks to goals from Tony Hains and Matthew Hanlan
And it showed as Neil Harris’s side, who swatted Bournemouth in the previous round, dominated from the off.
Lee Gregory, set up by Morison, should have scored from their first attack but somehow hit the bar.
And the Hornets were fortunate to be still level at the break after Adrian Mariappa appeared to handle in the box.
Referee Martin Atkinson missed that one after keeper Costel Pantilimon was sold short by Miguel Britos’s backpass and Gregory slid in to cause chaos.
Pantilimon was eventually able to dive on the loose ball but had been hurt and had to be stretchered off.
Steve Morison scored with just five minutes remaining
And replacement Gomes was quickly needed to bat a Gregory volley, again the result of good work from Morison, over the bar.
Watford felt they should have had a penalty early in the second half when Stefano Okaka clashed with Byron Webster but again referee Atkinson shook his head.
It looked like the lacklustre Hornets, who sent on skipper Troy Deeney to pep them up, might get away with a replay.
But Morison used all of his 33 years of experience to lose his marker at the back post and justice was done.
There was still time for Webster to bundle the ball into the Watford net again but Atkinson had spotted an earlier infringement.
It didn’t matter though as Watford had nothing left and tonight’s draw will be eagerly anticipated in this part of south London.
