Manchester United suffered their third defeat in a row after slumping to a 3-1 loss away at Watford.
Colombian international Juan Camilo Zúñiga came off the bench to score with his first touch after Marcus Rashford clawed United level in the second half.
Rashford, handed his first Premier League start of the season at the expense of Juan Mata, stabbed his close range effort past Heurelho Gomes to cancel out Etienne Capoue’s first half strike.
In truth it was Walter Mazzarri’s Watford side that dominated for the first 60 minutes of the game with Manchester United struggling to find their rhythm with Paul Pogba playing alongside Marouane Fellaini in the holding midfield role.
David De Gea twice came to the rescue for Jose Mourinho’s team to deny Watford, the most impressive coming against Troy Deeney’s powerful header coming shortly after Odion Ighalo provided the miss of the season so far after he skewed his shot wide of an open goal.
The performance of Manchester United captain Wayne Rooney will again spark a debate as the 30-year-old struggled in all aspects as he struggles to find his best position.
A string of misplaced passes and over-hit crosses summed up Rooney’s lack of confidence as he again failed to link up with Zlatan Ibrahimovic who endured a frustrating day of his own.
After Rashford’s equaliser United started to look the more likely to win the game after applying more sustained pressure but it was to be Watford’s day after Zuniga’s blistering impact.
Manchester United’s misery was compounded when Troy Deeney fired home from the penalty spot after a Fellaini foul.
