The on-loan youngster scored twice before the break to help the Hornets to a 5-4 half-time lead and then was the only player to hit the target in the second half.
Afterwards Watford boss Ray Lewington said: "There was some good forward play out there and Michael Chopra in particular has shown us what he is capable of after getting warmed up to the task last weekend.
"We moved the ball well in attack and took our chances when they came. I'm sure we've been creating a few chances like that in away games this season but (against Burnley) we had a striker in Michael Chopra who is a natural in front of goal."
Hopefully the goals will have clinched Chopra a place in Watford’s line-up for the FA Cup semi-final against Southampton.
