Sunderland boss David Moyes has said that his side deserved at least a point following the Black Cats' fourth defeat in the last five games.
The north east side went down 1-0 at Vicarage Road on Saturday courtesy of an average at best Watford display, which saw
"The players showed a lot of heart, big commitment right to the end," he told Sky Sports.
"We tried to find a way of scoring but it's been a problem for us recently. I don't think we deserved to lose the game. We deserved to get something out of it."
The Hornets' 58th minute winner resulted from Sunderland struggling to deal with a set-piece - something that has haunted them throughout this campaign.
Fabio Borini failed to divert his defensive header away from danger and instead cannoned the ball off his own crossbar, allowing Britos to take advantage of the looping rebound.
Even though the Black Cats showed costly frailties yet again, Moyes was pleased with his side's overall performance.
"We did well as we had to defend a few [set-pieces], especially in the first half. We just don't quite see the job through in the second half on one of them", the Scot added.
"They didn't really have any other real opportunities. Jordan [Pickford] made a great save in the first half, after that it was pretty even."
