A wonderful Jose Holebas goal was enough for Watford to beat Middlesbrough and move into the top half of the Premier League table.
The Greek wing-back struck a superb second-half strike from just outside the area which secured the Hornets all three points in a match lacking in any other moments of quality.
It was an intense start to the game, Deeney failing to get a shot off after fighting through the Boro defence, and Downing firing over for the hosts.
Gaston Ramirez also flashed a strike wide, as Boro started to show their dominance – a Behrami header was a rare chance for the Hornets.
