Walter Mazzarri is becoming frustrated with Watford’s defensive mistakes that cost them more points in the defeat at Stoke City.
Stoke ended a run of five games without a win as Ryan Shawcross and Peter Crouch netted in a 2-0 victory over the Hornets, who have won just one of their last eight matches.
Defensive mistakes cost them dear at the Bet365 Stadium with Adlene Guedioura losing Shawcross for the opening goal and Sebastian Prodl at fault for Crouch's second.
"I want to say we played well but we made two mistakes and they scored from both," he said.
"We could have scored before this but we didn't. We have demonstrated we can play in a difficult stadium against a tough team like Stoke.
"We have to now keep going. I am not happy but nothing is going our way. It's a period where we are not lucky. On top of this we have many injuries."
Mazzarri had stated after Sunday's 4-1 loss to Tottenham that he did not fear the sack, and here he pointed to the fact he believes the Hornets, who have been ravaged by injuries, are for once looking at a long-term project with him at the helm.
"I don't feel under pressure because I speak with the owner every day," said the Italian.
"We know what our objective is and we're not only looking at the next five or six matches, we are looking at the next three years.
"When you look at all the injuries we have, it is difficult to get results in the Premier League. Now we have to take this occasion to look and work for the future.
"The important thing is to keep fighting for the next games. I liked the way our fans behaved because they understood the moment we're in and they supported us until the end and this is very important for us.
"There were only two incidents for them that changed the result because they managed to score both. We were not lucky."
