Watford climbed into the top four of the Premier League after Tom Cleverley’s 92nd-minute goal gave them a 2-1 victory over Arsenal at Vicarage Road on Saturday.
Per Mertesacker headed Arsene Wenger’s side into a 39th-minute lead from a corner but Troy Deeney equalised from the penalty spot in the 71st minute after Hector Bellerin had bundled over Richarlison.
The game looked set to end in a draw until Cleverley pounced on a loose ball in the penalty area and drilled a shot high into Petr Cech’s goal.
Watford have now leapfrogged both Arsenal and Chelsea into fourth place, on 15 points, while the Gunners fell one place to sixth and remain on 13 points.
Wenger left Alexis Sanchez out of his matchday squad after his Chile side’s loss to Brazil on Tuesday ended their hopes of World Cup qualification. Mesut Ozil was sent on as a second-half substitute for Danny Welbeck but was largely ineffective.
Wenger was unhappy about Watford being awarded the penalty, saying: “It was a scandalous decision and there is little we can do about it.”
He added: “We panicked a little bit in the last seconds.”
Watford head coach Marco Silva said: “We are obviously happy. Our second half was really good. We have three important points and we want to stay in this moment.”
