Watford head coach Marco Silva's anger was palpable after Bristol City inflicted a "really bad" Carabao Cup second-round defeat on the Premier League side.
The Hornets, who had Etienne Capoue sent off, became the only top-flight side to be knocked out on Tuesday as the Robins' Niclas Eliasson scored the decisive goal in a 3-2 win at Vicarage Road.
"Bad night - a really bad result for us, a disappointing result," head coach Silva said of his first loss at the Watford helm. "Of course we prepared for the match to win and we knew what we needed to do to win, but we didn't do it.
"In the first half we controlled the match but we played very slow. Very, very slow, too slow all the first half."
