Sydney's long-time strength has become a glaring weakness as they aim to arrest a slump that has turned the perennial finalist into a bottom-four contender and raised questions about their short-term future.

When the Swans last faced Richmond in June, they were playing off for top spot on the ladder, but their performances since are not consistent with that of a side that will push for September.

The Swans have won just five of their past 14 games and the manner of some of those losses has sent alarm bells ringing.

The Swans were dominated in the clinches by Melbourne after half-time week, returning a contested possession differential of -31. The defeat could be characterised as un-Sydney-like, though it's become an increasingly familiar way for them to lose.
