"We were better than Watford," says the boss
Neil Harris could not hide his delight following Millwall's 1-0 Emirates FA Cup Fourth Round win over Watford.
Steve Morison slammed home the winner five minutes from time, ensuring a second Premier League scalp of the competition for The Lions.
The club will now feature in Monday night's Fifth Round draw.
"It's been a good week for us as a club," said Harris.
"I thought we was excellent today - outstanding. Individually and collectively, we were better than Watford.
"I said to the boys at half-time - that was an excellent first-half, but we could've been out of sight. If we want to progress as a group, we need to do exactly the same in the second-half and add that clinical touch. On the whole, I'm really pleased."
The Hornets made seven changes to their starting XI and were made to pay. Harris, however, was "surprised" at the team Walter Mazzarri put out.
"Watford played a strong side today. They've all played top level football regularly. We thought they'd make more changes, so the side surprised us a little. We've played two really good Premier League sides and kept two clean sheets, being relatively comfortable in both games."
"I certainly didn't want a replay. Walter probably didn't either, in what is already a busy February.
"I'm confident in my players ability and confident in them to come on and change the game. When you've got the quality of Shane Ferguson and Jed Wallace to come on with their delivery in wide areas, they're always going to give my strikers an opportunity. Moro and Gregs might miss once, maybe two, but they won't miss a third."
With many lower league sides and Premier League sides still left in the competition, Monday's draw could throw up many variations for Millwall.
The boss, though, just wants one thing.
"I'd like to be at home in the draw. I'm not fussed who we get, but I'd certainly like to be at home. There's a few sides who won't fancy coming here."
