Manchester United suffered their third straight defeat as Watford handed José Mourinho his worst run as a manager in a decade.
And the Special One says his team have got no luck.
Goals from Etienne Capoue, Juan Zuniga and a late penalty from Troy Deeney overwhelmed the visitors, who had levelled with a solitary strike from Marcus Rashford.
For all their possession, United were unsettled by Watford’s harrying game and went behind on 32 minutes after Anthony Martial, still groggy from an earlier clash of heads, was robbed by Miguel Britos.
Daryl Janmaat picked up the ball and crossed for Capoue to stroke in his fourth goal of the season.
After the break, United improved, but Watford keeper Heurelho Gomes denied Zlatan Ibrahimovic with a flying save.
The Red Devils always looked vulnerable and Zuniga scored from a cutback by Roberto Pereyra less than a minute after coming on.
Zuniga was then brought down by Marouane Fellaini inside the area late on to allow Deeney to score from the spot.
Jose says: “I reflect on three factors from the match, but only one of them I can improve.
“The first factor depends on ourselves, it relates to our individual mistakes and collective mistakes as individual players and as a team. We have to improve something, it is in our hands.
“The second factor is the referee and I can’t control their mistakes. The story of the game is the result and not the ridiculous situation of the first goal.
“The third factor is luck, we didn’t have it. We were the best team when we lost.”
