David Moyes was left frustrated following Sunderland's narrow 1-0 defeat at Vicarage Road.
The Black Cats had chance in an open first-half as the 'keepers came out on top, but they were dealt a blow moments before the hour mark as Miguel Britos headed home.
Adnan Januzaj went close on two occasions as the Watford backline battled until the death, with Fabio Borini denied by Huerelho Gomes late on.
And speaking post-match, Moyes said his side deserved something from the game.
"The defeat is a little bit harsh on us, I think we deserved something out of the game from the performance we gave and the way the lads stuck at it.
"We defended set pieces well; that was a big test for us as Watford have some big players in their side."
He continued: "I was frustrated by the lack of chances we created; that’s been a problem for a while for us.
"The subs we made did well, [Didier] Ndong and [Wahbi] Khazri brought something new to the game when they came on.
"At that point we were a goal down and we pushed for an equaliser but it wasn’t to be.
"There’s no time to dwell though as we must go again on Tuesday; we pick ourselves up and I’ve told the players that.
"We wanted a win from one of these two games and we didn’t get it today, we came close to getting something, but we’ll have to try and get it on Tuesday against Leicester now.
"We deserved a point at least today, I thought we stuck at it and we need to make more of our performance next time out."
