Sunderland manager David Moyes said Saturday's home 0-0 draw against Burnley "isn't enough" as his side slumped closer to Premier League relegation.
Moyes was frustrated after bottom-of-the-table Sunderland failed to make the most of a game against a team without an away win to their name in the league all season.
They are now seven points off safety and Moyes said of the result: "It's not enough -- it would have been down as one of the wins in my book, so now we have to turn one of the draws I had down into a win.
