Harry Kane rages — shot unexceptional (2,5,6)
I believe the answer is:
no great shakes
'unexceptional' is the definition.
(thesaurus)
'harry kane rages shot' is the wordplay.
'harry' is an anagram indicator (harry can mean to attack or spoil).
'kane'+'rages'+'shot'='kaneragesshot'
'kaneragesshot' anagrammed gives 'NO GREAT SHAKES'.
(Other definitions for no great shakes that I've seen before include "(small beer)" , "Little tremors" , "unremarkable" , "Nothing out of the ordinary" , "Insignificant" .)
