Elias Kachunga ended struggling Huddersfield’s long run of 738 minutes without a goal on their travels.

Aaron Mooy’s late spot kick saw the Terriers’ hit four goals on a top-flight opponent’s ground for the first time in more than 60 years.

Watford skipper Troy Deeney saw red as the Hornets had a player sent off for the THIRD game in a row.

Town captain Jonathan Hogg followed him after two bookings on his return to his old club.

And referee Michael Oliver and his assistants must have been red-faced when they watched replays of Kachunga’s first goal of the season that set the Terriers up for their only away win since the opening day of the season!

Watford manager Marco Silva has now seen his side have four players sent off and pick up only one point out of the last 15.

But he refused to get drawn into a war-of-words about the officials even though his body language reflected his disbelief at the first goal and Deeney’s red card.

He said: “I don’t want to talk about the officials, of course, I have my opinion but at this moment I don’t want to talk about it.

“I’m sure we don’t have a disciplinary problem, I’m sure about that. We can talk about the red cards but I’m sure we do not have an issue.

“With my feeling now it’s better that I don’t talk. It is the same as with the first goal, you ask me about that because you know what happened and you know what happened with the red. I don't want to talk about officials.

“I can’t talk about the situation, it is not what I can control. My job is to do my best to get good results.”

 “I agree it was our worst performance of the season. We didn’t start well, we didn’t perform at our best.

“You can talk a lot of things about the match but first of all we didn’t perform. We made mistakes which we cannot make.

“We cannot change the result, now is the moment for us to keep focussed and prepared for the next game.

“Our players have already started to understand after the match where we went wrong.”

The Yorkshire side arrived at Vicarage Road not having scored on the road since their opening day 3-0 victory at Crystal Palace.

Since celebrating their return to the top-flight after a 46-year absence they had gone eight away matches in all competitions without hitting the back of the net.

Admittedly there was more than a slice of luck about the sixth minute opener. Replays showed that Collin Quaner, who poked the ball through to German-born forward Kachunga, was offside after the Hornets messed up at least three chances to clear a corner.

And there was no-one between the Congolese international and the goal when he poked home from a foot or so with keeper Heurelho Gomes ahead of him.

No wonder boss Silva had a face like thunder in the technical zone and it’s hard to figure out why the officials blundered so badly when it was such a clearcut decision.

Fortunately there was no dispute about Town’s superiority until they were also reduced to ten men although Watford shot themselves in the foot.

Fingers had to be pointed at defender Adrian Mariappa, badly at fault for the second, completely miskicking as he tried to clear Quaner’s cross.

Mooy was left to bundle the ball past Gomes and another defensive mishap let in Laurent Depoitre for the third.

Gomes, who hardly distinguished himself, left him far too much space to fire home after Jose Holebas had initially won the ball but then crumpled to the turf, allowing the Belgian to follow up his midweek goal against champions Chelsea with his fourth of the campaign.

Watford fans were given hope of a nerve-tingling comeback when Abdoulaye Doucoure, who earlier had picked up his fifth yellow and an automatic ban, rifled home from outside the box with 22 minutes left.

It was short-lived though as Doucourie brought down Depoitre and Australian Mooy sent Gomes the wrong way to complete a personal double.

Terriers’ boss David Wagner said: “I’m impressed with what the players have shown, even if I wasn’t surprised.

“Before the game I saw some stats that the team has not gone that long without scoring ever and this only shows how crazy football is sometimes.

“We didn’t look like a team that’s lost four in a row and this is one of their qualities.

“We have known if we perform our best we have a chance. It doesn’t matter what happens in the past.

“A lot of people didn’t expect us to be where we are at the minute, we are so calm because we know exactly what size club we are.

“Our budget is not comparable to any other club but our ambition is. It’s only just the middle point of the season, not more, and we have to improve.

“It’s difficult to highlight one individual, I’m delighted over the moon, for the supporters, I’m very proud.”

“It was, for sure, one of our best performances because we have had found difficult to score, we were clinical.

“The extraordinary thing for me is to perform like we did, it shows mental strength. They are mentally so strong they don’t get dragged too far away after negative moments.”

Wagner fears that Kachunga, who broke his Premier League duck, could be a long term casualty admitting: “It looks like a serious knee injury but we have to make further investigations.”
