Sebastian Larsson has told the Daily Telegraph clubs battling relegation "will be worried" by Sunderland's track record of beating the drop.
Sunderland are currently bottom of the Premier League but are just two points behind 15th-placed Middlesbrough after securing a draw against Tottenham and a 4-0 win over Crystal Palace in their last two games.
Larsson has played a part in many relegation battles since joining from Birmingham in 2011, with the club finishing three points clear of relegation in 2012-13, five points clear in 2013-14, three points clear in 2014-15 and two points clear last season.
