Brentford boss Thomas Frank was in an ecstatic mood after his side beat Watford 2-1 at home to get back to winning ways in the Premier League.
The Bees bossed the second half but were unable to respond to Emmanuel Dennis' first-half header until Pontus Jansson headed home six minutes from time.
Having been denied victory last week at Leeds by a Patrick Bamford leveller in the 94th minute, Brenford seized all three points in the 95th when Bryan Mbeumo converted from the spot after Saman Ghoddos was felled by William Troost-Ekong.
