It was one of the most extraordinary football matches played any time, any place, anywhere and a personal triumph for Michael Chopra.
Chopra, on loan to Watford from Newcastle scored four to edge Burnley's hat-trick hero Gareth Taylor in the man-of-the-match stakes.
They were nine goals in the first half and when the tenth one went in there was still half an hour to go.
Unfortunately many Burnley fans missed out for they had headed to the exit door long before half time.
Wayne Brown gave Watford an early lead, Taylor equalised but goals in quick succession from Micah Hyde, Neil Cox and Chopra put Watford in the box seat.
Steve Davis and Taylor again gave Burnley hope before Chopra grabbed his second five minutes from the break.
An incredible first half ended with Taylor completing his hat-trick and the big striker twice went close to making it five all soon after the break.
But Chopra was determined to be the star of the show and two further goals gave the score line a disastrous look from the Burnley standpoint.
Burnley manager Stan Ternent said: "I couldn't believe what I was seeing, but we gave goals away with some schoolboy errors. It was incredible." Watford manager Ray Lewington said: "I have never been involved in a game like it in my career.
"It would be easy to pick holes in the defending from both sides. But I would prefer to concentrate on the finishing, some of which was top class."
