Watford's promising start to the season has come to a dramatic halt after they were knocked out of the Carabao Cup after losing to Championship side Bristol City 3-2.
The Hornets, who secured a draw with Liverpool on opening day before defeating Bournemouth on Saturday, went ahead after some interplay was finished off by Etienne Capoue.
However, the Robins, who had made nine changes from their clash with Millwall, equalised through 18-year old Freddie Hinds.
Marco Silva's side was left stunned when they went behind following Bobby Reid's instinctive finish on the 67th minute mark.
Niclas Eliasson secured City's passage through to the third-round in injury time, before Adrian Mabiappa grabbed a consolation goal for Watford.
Watford will be at home again this Saturday when they take on Brighton & Hove Albion, who are yet to register a goal so far this season.
