Gomes pulled off a few great saves to keep Watford in the lead, and helped his side secure all three points.
It was a big win for Watford, putting the team in 10th place in the Premier League.
"It was important, those saves," said Silva.
"Heurelho has been performing really well, has done everything really well this season.
"Here, no one wins alone and no-one loses alone. Gomes did everything I expect. Aside from that, it's the game. The first thing I can say he is a leader and a great professional, and he was great for us."
