Sunderland manager David Moyes said his side's "dire" performance in their 4-1 loss at Burnley was as bad as any during his time in charge of the club.
The Black Cats end 2016 in the Premier League relegation zone after Burnley's Andre Gray scored a hat-trick and Ashley Barnes converted a penalty.
"It was a poor performance - really, really bad - and defensively we were all over the place," said Moyes.
"The players have to take responsibility as well as me."
