Steve Bruce could barely stop smiling as his Hull side ended a 25-year wait for a win at Elland Road to underline their promotion credentials.
Despite the tight nature of their 3-2 win over Leeds, the in-form Tigers were better than a one-goal margin and after recovering from conceding a sixth-minute penalty goal to Luciano Becchio, were in fine touch.
Ahmed Elmohamady, Abdoulaye Faye and Robert Koren all scored before Andy Gray's flattering consolation, leaving Bruce pleased with his new-look side.
City started slowly following Bruce's summer arrival but are on-song now, with this victory backing up their 4-1 mauling of Millwall on Saturday.
"Without a question we deserved it. We had to recover from an awful start," said the former Sunderland manager.
"I've looked back, it wasn't a penalty. It was outside of the box and to recover the way we did was terrific. And some of the football we played...
"We are open at times, but the players are enjoying it and I am enjoying watching them. You don't win at Elland Road very often. The players can enjoy it. We have played well at home, but to come to a big stage and play the way we have is pleasing."
While Bruce headed back down the M62 in high spirits, opposite number Neil Warnock was left to rue the depth of his squad.
On a night when fans protested about owner Ken Bates' perceived lack of investment, Warnock revealed he expects striker Ross McCormack to be missing for as long as two months with an ankle injury.
He does not expect to replace the Scotland international either, saying: "People ask me if I'm going to be on the phone tomorrow. I might as well go fishing. All my targets have gone. Ross might need a little bit more surgery this week. It's as bad as you can get for a twisted ankle."
