Watford produced an impressive display at Turf Moor as Andre Gray, Troy Deeney and Will Hughes all got themselves on the scoresheet to seal a comfortable victory.
Gray came back to haunt his old side by producing a smart finish beyond Joe Hart to open the scoring after just three minutes on the clock.
But the visitors' lead did not last long. Three minutes later and it was all square again. Johann Berg Gudmundsson swung in a corner, Ben Foster was undecisive and stranded, James Tarkowski was the opposite and leaped to meet the ball and thunder in an equaliser.
The sides went in level at the break but it was Watford who got started the second half as they started the third with Troy Deeney restoring their lead in the 48th minute. Minutes later it was game, set and match with Hughes joining in on the party by scoring Watford's third and sealing the points.
