Football or cricket team’s prime? (6)
I believe the answer is:
eleven
I believe this is a double definition.
'football or cricket team's' is the first definition.
(I've seen this before)
'prime?' is the second definition.
(I've seen this before)
(Other definitions for eleven that I've seen before include "Time for the mid-morning tea break?" , "Not first team (6,6) - See 24" , "football team, for example" , "Enough for a team" , "Lowest two-digit prime" .)
