Russell Martin admits the body language of some of his Swansea City players prior to Birmingham City's late equaliser in the meeting between the sides typified their side's defensive struggles this season.
The Swans looked on course for all three points at St Andrew's after goals from Olivier Ntcham and Matt Grimes put the visitors 2-1 up following Scott Hogan's opener for the hosts.
But Troy Deeney netted in the final minute of regular time after Swansea failed to clear their lines from a set-piece as John Eustace's men claimed a point.
