Watford swept aside a below-par Barnsley side with a breathtaking display at Oakwell this afternoon.
The visitors made a dream start when Deeney grabbed his first goal in five matches with a low drive from close range in the ninth minute.
However, the lead lasted just five minutes, as Jason Scotland capitalised on Iriney's mistake to fire a shot across Manuel Almunia.
Watford were back in front in the 18th minute though, as Faraoni volleyed home Lewis McGugan's deflected cross from the left wing.
With half time approaching, Forestieri turned home a cross from the right wing to extend Watford's lead.
With 20 minutes remaining, Sean Murray ensured his side would be going home with all three points with a crashing drive from 20 yards.
The best goal was saved for last though, as Ikechi Anya ran the length of the pitch before wrapping a delightful finish in the corner of the net.
