The Baggies remain in eighth place - a position they have held since December - but they have now only won once in five league matches. The Hornets are one place behind and now 10 points clear of the relegation zone. Watford had been creeping into danger after a four-match winless run in the league. Their fears were eased after Saturday's narrow victory over struggling Sunderland, and now only a major capitulation would see them sucked back into the relegation battle with eight games remaining. Niang's special opener, which was set up by Deeney, got Watford off to the best possible start and they remained in control of the first half. Deeney extended their lead when he latched on to a looping ball and scuffed home, while managing to avoid an on-rushing Ben Foster.
It looked like it was going to be a routine victory before Britos' red card, and although the defence had to scramble at times, West Brom failed to capitalise on the extra man. The Baggies have been safely tucked away in mid-table for most of the campaign and had taken points from both Arsenal and Manchester United in recent weeks. But Tony Pulis' side have now only won one away match from their last 10 and have failed to score in four of their last five games. They offered very little in the first half at Vicarage Road and Pulis made all three substitutions before the 60-minute mark in a bid to rescue the game. Once Watford were down to 10 men, the visitors were in the ascendency but Rondon could only head over the bar, while James Morrison fired well over in injury time.
