Richarlison scored an injury-time equaliser as Watford came from two goals down to save a point at West Bromwich Albion.
The Baggies scored twice in three first-half minutes through Salomon Rondon and Jonny Evans, before Abdoulaye Doucoure reduced the deficit before the break.
The hosts looked set to record a first Premier League win since 19 August when Brazil Under-20 international Richarlison connected with a Jose Holebas free-kick deep into added time to deny the hosts.
The result means Watford maintain their unbeaten record on the road this season.
‘We kept believing’ – what they said
Watford midfielder Abdoulaye Doucoure: “You could see with Jose Holebas he was tackling five minutes before and then got the assist. We kept believing until the end and that’s what you get.
“We have to be thankful for the fans because they’re always behind us.”
