Beppe Sannino admits Watford were not at their best in the goalless draw at Yeovil Town but he believes some of his players were suffering from fatigue in the second half at Huish Park.
An end to end contest lacked quality in the final third with neither side able to create the decisive chance to seal all three points.
The Hornets have played four games in the past 11 days and Sannino suggested the busy schedule goes some way to explaining why the visitors' faded slightly in the second period.
"I think the game was split into two halves," said Sannino. "In the first half we were the better side and in the second half we could have done better.
"It’s not an excuse but maybe the fatigue set in a bit because we have been playing a lot of matches."
Sannino continued: "My players are playing a lot of matches in a short space of time and in my opinion this was the main factor but I know today there were a lot of Watford supporters who came and they perhaps deserved a little bit more from us.
"My players though are only human and I think it is understandable that on a heavy pitch they felt a bit tired in the second half."
Watford have now registered three clean sheets in a row in the Championship but their performance was lacking in punch and creativity.
When asked if he was concerned by the team's lack of clear-cut opportunities, Sannino said:
"My main concern is not about creating chances.
"Because we are playing a lot of games in a short space of time my main concern is giving the players the right time to recover and picking the best eleven for the game.
"It’s true what you say about us lacking today in our final pass and I am aware about that but it is not my primary concern at the moment."
He added: "We always play to win the game because we want to repay the supporters for what they do for us."
Watford were perhaps unfortunate not to be awarded a penalty in injury time as Davide Faraoni ran at Jamie McAllister and the ball appeared to pop up on to the Yeovil captain's hand.
Sannino said: "What the lads said to me in the dressing room is that it was a handball but I want to look forward, I don't want to blame the referee."
The Hornets move up to 11th in the Championship, eight points behind the play-offs, and are 20 points ahead of Yeovil who remain rooted to the bottom of the league.
Sannino insists he was not surprised by the Glovers' gutsy display and believes even if his team were unable to seal a win, it was important to take something from the match.
"When you don’t win, you have not to lose," he said.
"In this Championship there is not an easy game even if there are teams in different positions in the table.
"It’s true there are teams who are fighting relegation and teams who are wanting something more.
"You have to show that on the pitch though and there is no easy formula."
