Emmanuel Dennis' second-half goal wasn't enough for Watford to avoid defeat against Brentford at Vicarage Road, as goals from Christian Nørgaard and Pontus Jansson condemned the Hornets to a 10th straight loss at home.
Nørgaard's tap-in put the Bees ahead in the first half in a relatively even battle.
Dennis and Watford responded well and threw caution to the wind to find a second goal, before Jansson's stoppage-time header against the run of play handed Brentford a winner.
A slow start for both teams saw little action in the opening stages of the game, Christian Eriksen’s off-target curler the first attempt of the afternoon. Ismaila Sarr headed over minutes later after Kiko Femenia’s clever delivery into the box, with possession mainly in Brentford’s defensive third.
The Bees took full advantage of the next chance they received, however. A long throw-in from Ethan Pinnock was met by Kristoffer Ajer’s flick-on, and amidst a packed six-yard box Nørgaard tapped home for an early lead.
