We conceded early first again - against the run of play - but looked good when Heung-Min Son levelled on 25 minutes.
We looked on course going into half-time and in the early stages of the second half but Davinson Sanchez was sent off on 52 minutes and that brought Watford back into the game.
Nevertheless, our 10 men defended well for the following 42 minutes and we always tried to push on for a winner without creating too many clear-cut chances. Watford hit the bar, Moussa Sissoko went closest for us with a shot into the side-netting.
