Delirious, seeing entire chaos in football club (8)
I believe the answer is:
frenetic
'delirious' is the definition.
(thesaurus)
'entire chaos in football club' is the wordplay.
'chaos' is an anagram indicator.
'in' indicates putting letters inside.
'football club' becomes 'FC'.
'entire' is an anagram of 'reneti'.
'reneti' put into 'fc' is 'FRENETIC'.
'seeing' acts as a link.
(Other definitions for frenetic that I've seen before include "Maniacal" , "Mad" , "Re-infect, being quite frenzied" , "Fast and wild" , "Extremely agitated -- if recent (anag)" .)
