Watford secured a comeback victory against a lacklustre Everton side who surrendered an early lead at Vicarage road.
Ronald Koeman's men looked set to build upon their recent draw to Manchester United after taking the lead against the Hornets through Romelu Lukaku - but a second half meltdown would soon see the Toffees on the back foot.
Watford retained composure and struck back, first though a sublime near-post flick from Stefano Okaka before Austria Sebastian Prodl powered home a header from a dangerously placed free-kick taken by Jose Holebas.
The Hornets made the Toffees pay for weak set-piece defending by adding a third, Okaka getting himself on the score sheet for a second time, tucking away a corner to give Holebas assist number two.
