Watford overcame Manchester United at Vicarage Road to continue Jose Mourinho's nightmare week, with the 3-1 defeat sending the Red Devils to three defeats in a row.
Etienne Capoue put the hosts in front in the first half, before Marcus Rashford capitalised on a loose ball to equalise.
However, Juan Camilo Zuniga - on as a late substitute - sent the Hornets back in front with seven minutes left, and when the same player was fouled inside the area, Troy Deeney stepped up to convet the resultant penalty in the dying seconds.
