The forward believes working hard and playing like a team turned things around against Leeds United.
The Hornets went 2-0 down after Billy Sharp and Rudy Austin had scored for Leeds, but the promotion-chasing club turned things around in dramatic style.
Troy Deeney halved the deficit shortly before half-time and a second-half brace from Vydra broke Leeds hearts and ensured Watford climbed to within a point of second-placed Middlesbrough.
Leeds looked like they would win with ease after poor defending allowed them to take a two-goal advantage, but Vydra has explained how his side ultimately claimed the victory.
“The first 20 minutes weren’t good for us,” he said, “but we played like a team with a lot of hard work and it changed the game, so we are happy.”
Leeds’ players have recently been praised for their team ethic but it was Watford who demonstrated that on Saturday, fighting back from a losing position and leaving the Whites’ manager Neil Redfearn to reflect on two defeats in a week following the 2-0 loss to Brighton & Hove Albion.
