Crack team she can set on Englishman (9)
I believe the answer is:
sassenach
'englishman' is the definition.
(Sassenach is an example)
'crack team she can set' is the wordplay.
'crack team' becomes 'sas' (Special Air Service, crack team of soldiers).
'set' is an anagram indicator (instruction to set the letters).
'she'+'can'='shecan'
'shecan' anagrammed gives 'senach'.
'sas'+'senach'='SASSENACH'
'on' acts as a link.
(Other definitions for sassenach that I've seen before include "In Scotland, English" , "Englishman, Lowlander" , "Englishman in Scotland" , "Lowland Scot" , "Uncomplimentary Scots term for an Englishman" .)
