Watford boss Javi Gracia is confident his side can beat Manchester United on Saturday.
United travel to Vicarage Road hoping to disrupt the Hornets perfect start to the season.
"They are a very good team and they finished last season second. They have a very good coach and and I know it will be a very, very demanding game," Gracia said.
"When we are at home we feel confident and feel we can compete and get every point. In this moment the results help us feel we can beat them.
"We will need to play well, run a lot, fight a lot and we will prepare for the game as well as possible."
