Crawler today is in disarray (5)
I believe the answer is:
toady
'crawler' is the definition.
(I know that crawler can be written as toady)
'today is in disarray' is the wordplay.
'is in disarray' is an anagram indicator.
'today' with letters rearranged gives 'TOADY'.
(Other definitions for toady that I've seen before include "Obsequious person" , "Curry favour" , "Obsequious type" , "Creep" , "fawn" .)
