Norwich City defender Michael Turner has warned Sunderland they could go down.
Turner is adamant his former club is not too big to drop out of the Premier League.
"No, I don't think you can be too big a club to go down," he said.
"If you look at teams in previous years who have gone down, you would never have thought it at the start of the season.
"When you are on a bad run it's difficult to pick up points and every team in and around that position needs to fight hard to pick up anything."
