Neil Warnock was not interested in the result as his Leeds side were thrashed 6-1 by Watford, admitting he lost interest in the game after seeing midfielder Rodolph Austin suffer a suspected broken leg.

United were a man and a goal down when the Jamaica international fell to the floor amid a melee from the corner, having earlier gone behind to Matej Vydra's opener and lost Jason Pearce to a straight red card for a foul on Almen Abdi.

"I'm not devastated about the game but I am about Rudy, he has broken his leg in two places. We had made the subs and I wasn't bothered, I thought the game of football was irrelevant," he said.

In response to the sending off, Warnock adopted the cavalier approach of making all three of his substitutions by the time the second half had started so, when Austin was carried off on a stretcher two minutes after the restart, his side had to play the remaining time with nine men.

They were duly run ragged, with Vydra scoring again alongside goals from Abdi, Mark Yeates, Sean Murray and Troy Deeney. Michael Tonge's penalty was Leeds' sole response.

Leeds have yet to officially confirm the nature of the former SK Brann player's injury, but Warnock added: "I was told it was a double fracture but he shouldn't have been in that position (covering for Pearce at centre-half).

Watford manager Gianfranco Zola admitted he had taken a risk by employing such an attacking formation from the off, but was pleased to reap the rewards for his boldness.

The Italian looked to counter Leeds' three-at-the-back set-up by going with a three-man attack and, after weathering an early storm when United hit the post, they were able to cut loose as the game went on, especially as Leeds' numbers dropped.

"We took a gamble in the first half, we made changes and we knew we would risk something at the back," he said.

But the Italian added: "It was a very good result, I am pleased for our strikers because we needed a confidence booster and this will provide it. To be honest, the fact that they had nine gave us a big advantage, but we did very well and used the extra man wisely. It proved to be a very good day for us."
