Watford boss Walter Mazzarri is confident of victory over Everton.
Mazzarri believes if his Watford side perform to the same level they did at West Brom last weekend, they will pick up three points against Everton.
He said: "In the last two games, we lost, but we shouldn't have. Mainly the last one, we deserved to win - in the Premier League there are times where you have more or less luck which can win or lose you games.
"If we play like we played against West Brom, we will manage to win."
