Football team stopped by for one or two? (7)
I believe the answer is:
integer
'two?' is the definition.
(two is a kind of integer)
'football team stopped by for one' is the wordplay.
'football team' becomes 'inter' (short for Inter Milan, Italian football team).
'stopped by' indicates putting letters inside (I've seen this in other clues).
'for one' becomes 'eg' (both can mean 'for example').
'inter' going around 'eg' is 'INTEGER'.
'or' acts as a link.
(Other definitions for integer that I've seen before include "Result of counting" , "Get Erin (anag)" , "Perhaps 60,000" , "The whole thing" , "One for example" .)
