The battle between the two promoted teams produced end-to-end action at Carrow Road, and the result leaves Norwich rooted to the bottom of the standings without a point.

Watford took the lead in the 17th minute when right back Kiko Femenia delivered a sumptuous cross into the box and Emmanuel Dennis found a sliver of space between the Norwich centre backs to head home.

Teemu Pukki equalised when he got in behind the Watford defence and latched on to Mathias Normann's pass before curling the ball around goalkeeper Ben Foster.

Sarr nearly put Watford 2-1 up on the stroke of halftime only to be denied by goalkeeper Tim Krul. But the Senegalese forward came out in the second half and scored first from a Joshua King cutback and then by pouncing on a rebound to guide the ball into an empty net for his second.

The result ended Watford's three-match losing streak and moved Xisco Munoz's side up to 10th in the standings. (Reuters)
