Watford 3-0 Leeds United
New Leeds owner Massimo Cellino was at Vicarage Road to see his side thrashed by play-off chasing Watford.
Cellino confirmed earlier in the day that he had completed his controversial takeover of the Elland Road outfit.
Almen Abdi gave Watford an early lead when he nodded home Ikechi Anya's cross, before Anya headed the second from Marco Davide Faraoni's centre.
Troy Deeney's close-range strike left Watford seven points off sixth with a game in hand. Leeds have one win in 12.
Indeed Leeds could count themselves fortunate their latest setback was not even heavier.
Keeper Jack Butland had to deny Deeney, who also saw a late effort sail narrowly wide.
Noel Hunt failed to convert Leeds' only decent chance, provided by Dominic Poleon, early in the second half. And the striker nearly landed himself in trouble with a late challenge on Faraoni that earned him a yellow card.
Watford remain unbeaten at home since January 11 and are now seven points off the final play-off spot with a game in hand.
Watford manager Beppe Sannino: "I don't like to speak about the play-offs. I like to speak about the next match.
"It was a good win. Now we have six matches to play and hope to collect as many points as possible."
Leeds manager Brian McDermott: "Of course I'm under pressure - results suggest that.
"I'm not in a strong position now because of the results we've had over a period of time.
"I met [Cellino] before the game. We just talked about football. He's not looking to give me any assurances - I wouldn't expect any.
"He's an ambitious man; that's certainly not the sort of performance he wants to see.
"There's a big job here. It's a big club and there's a lot to be done, but he's got the clout to do it."
