Angel Rangel has warned Wigan they will face a Swansea side determined to showcase their unity at the Liberty Stadium on Saturday.
When Swansea finished 11th in the Premier League last season, it was based on a solid defensive foundation which yielded 14 clean sheets.
This season the south Wales club have not been as watertight and have conceded 11 goals in their last five games.
Defensive woes
Rangel does not believe all the blame lies with the back four, but admits it is important for Swansea to start registering clean sheets again.
"Maybe we don't press as much as last year but you don't concede goals because the defenders are playing badly just as you don't score goals because the strikers are playing well," he said.
"We are a team and sometimes we have been unfortunate with individual mistakes.
"We are not giving that many chances away, teams have just been clinical.
"Hopefully we won't give so many chances away and at the other end we have to score.
"We have to work on keeping clean sheets now because that is important."
