Boothroyd helped the Hornets reach the Barclays Premier League with promotion via the play-offs two years ago.

Brown is now hoping to do exactly the same this season as Hull bid to reach the top flight for the first time in the club's 104-year history.

"He [Boothroyd] has already sampled something I haven't and that's promotion to the Premier League," said Brown ahead of the trip to Vicarage Road.

"He's already had a year in the Premier League, so he's got more experience than I have in terms of management.

"I would like to achieve what he's achieved so far.

"But we are locking horns and there will be no love lost on Sunday, or certainly no love lost on Wednesday [in the second leg], but after the game we will have a beer there's no doubt about that.

"He's a great coach. He's a great motivator. He's a young manager compared to the majority of us.

"I'm looking forward to it. I think both games will be a great spectacle and may the best team win on both occasions."

Former Hornets striker Marlon King, who joined Wigan in January, scored the only goal of the game on Hull's last visit to Vicarage Road back in October.

It was a different story when the sides met just over a month ago in the return fixture at the KC Stadium, the Tigers running out comfortable 3-0 victors thanks to goals from Michael Turner, Fraizer Campbell and Caleb Folan.

Brown is keen to stress that will count for nothing and insists the form book goes out of the window as Watford go into tomorrow's game with just one win from their last 14 games.

"I think the 3-0 defeat will be fresh in their mind and so they will come back against that," Brown added.

"We've both got zero points and it's the start of the season again. The slate has been wiped clean.

"They'll approach this game in a fresh manner and with a fresh mentality and I fully expect Adrian Boothroyd's team to be rolling their sleeves up and throwing everything at us, the kitchen sink and all.

"But then they'll be coming back to the KC Stadium and have the kitchen sink thrown at them. It's just about the mentality of the players when they cross the white line.

"I fully expect it to be a tough game at Vicarage Road. We've got to make sure we come away with something to hang onto."

Reports have suggested on-loan striker Campbell, who has scored 15 goals since joining Hull in October, is set to feature heavily for parent club Manchester United next season, scuppering any hope Brown would have of re-signing the 20-year-old.

But Brown would only add: "As I've said all along, I think it would be remiss of my to talk about players' futures until after hopefully May 24 [the play-off final].

"There's going to be speculation and paper talk and there's not a lot I can do about that."
