Watford boss Slaven Bilic said his players now face the challenge of maintaining the standards they have set themselves after a 4-0 win at Stoke.
He only had a few days to work with the squad, but they responded with their best win of the season so far.
"A great win - and good for the players to get that little bit more confidence and believe they have class," he said.
"It's my job, me and my staff, to use this to show them what they have to do every day in training to be in a position to play like this.
