Watford manager Quique Sanchez Flores apologised to the Hornets' fans after their 2-0 defeat away at Southampton, saying it was their worst performance of the season.
Goals from Shane Long and Dusan Tadic were enough to seal the game for Southampton in what was a surprisingly easy victory for the Saints, with the home side barely having to break sweat in order to win the match.
So poor was Watford's performance that they managed just one shot on target, and that arrived after 84 minutes - with a 30 yard strike from Craig Cathcart which Fraser Forster easily stopped.
Speaking after the game to BBC Sport, Flores took the opportunity to apologise to the away fans, claiming the performance he'd just witnessed from his side was completely unacceptable, and that his team were simply second best to their opponents.
"We didn't hit the level of other matches," Flores said. "We didn't play well. It was the worst match we've played in the Premier League. Southampton played much better.
"I am sorry for the first half. I apologise to the fans. It's the first time in the season we failed to find the level.
"We didn't play our style on the pitch. The players can make mistakes - it's football."
Watford have now gone four Premier League games without a win in what is their first real dip in form all season, but two of those matches were one goal defeats to Manchester City and Tottenham Hotspur, and the other was a draw with current champions Chelsea.
The result leaves the Hornets in 10th, down a place from where they started the match, with 29 points from their 21 games played so far this season.
Their next two Premier League fixtures resemble winnable games however, with the first being an away trip to struggling Swansea City, while the second is a home tie against Newcastle United.
