Watford manager Quique Sanchez Flores: "We tried to go for the win but Sheffield United are a very confident and physical side. We didn't concede in a long time, so that's a good thing.
"The players responded really well and we need to support them. They were a little nervous with decision-making, everything is so fast, but I think we had opportunities that we can work on.
"A clean sheet is a good thing and we talked last week about not conceding. We're working hard together to get more confidence for the future.
"We have the break now with a lot of nationalities in our team, so we will come back and continue to work hard."
