Watford head coach Walter Mazzarri was angered by his side's display in the 1-0 defeat to Sunderland at the Stadium of Light.
Nordin Amrabat was denied a brilliant opener for Watford inside two minutes by an excellent save from Jordan Pickford, while Daryl Janmaat and Odion Ighalo were also thwarted by the goalkeeper as they failed to cancel out Patrick van Aanholt's opener.
The result left an embittered Mazzarri furious with his players for failing to secure a result, stating they only had themselves to blame for defeat.
"We did everything ourselves and I'm very angry.
