Paulo Pezzolano felt Watford's 2-1 victory against QPR was an important morale-booster for his players.
It was the Hornets' first win since Pezzolano took over as head coach this summer, when he replaced Tom Cleverley.
"I'm very happy, especially for the players because they needed this," Pezzolano told BBC Three Counties Radio.
"You need these victories to sustain the process. What's important to us is to build the process - for the players to understand what we want and how we're going to do it. That's a long process and it's a long season.
