Sheffield United manager Paul Heckingbottom was asked after the game about the Watford winner, and the fact their corner routine seemed to be partially hampered by the referee.

“You lot are trying to get me into trouble,” he said, referring to referee Josh Smith seemingly being in the way as the corner was played out to the edge of the box.

“I don’t think the move happens without his involvement. From then on we’re just trying to recover and stop the danger. It’s fine margins really.”

The Blades boss said he thought his side had a right to feel frustrated.

“I knew we’d have to play a lot on the counter, and it turned out that way. I thought, on the whole, we defended pretty well. When they attacked I thought we had the cover there.

“So it’s frustrating to get undone in the game by a goal like that.

“We weren't at full strength and there were a lot of good performances through our side, so it’s disappointing to come away with nothing from the game.”

Heckingbottom paid tribute to the Watford forward line.

“We knew the threat of Watford,” he said. “Their front three at the minute are probably the best and most dangerous in this division. They can cause you real problems, both individually and as a forward three.”
