A difficult situation for all there, you say (4)
I believe the answer is:
hole
'a difficult situation' is the definition.
'all there you say' is the wordplay.
'all there' becomes 'whole' (I've seen this in another clue).
'you say' indicates a 'sounds like' (homophone) clue.
'whole' is a homophone of 'HOLE'.
'for' is the link.
(Other definitions for hole that I've seen before include "Aperture; cavity" , "Well" , "mess" , "Hollow, cavity" , "This in one is a golfer's dream!" .)
