Under-fire manager Bob Bradley accepts Swansea will be relegated if they continue to defend as they have done during his two months in charge.
Swansea head into a crunch clash with fellow strugglers Sunderland at the Liberty Stadium on Saturday with statistically the worst defence in the Premier League.
The Welsh club have conceded a league-high total of 31 goals -- 19 of those coming in the seven games Bradley has overseen since succeeding Francesco Guidolin at the start of October.
Swansea returned to the bottom last weekend after a 5-0 mauling at Tottenham, but victory over Sunderland would move them above David Moyes' Black Cats and even out of the relegation zone if other results were to go in their favour.
