Broadcast inside team's ground (11)
I believe the answer is:
disseminate
'broadcast' is the definition.
(I've seen this before)
'inside team's ground' is the wordplay.
'ground' indicates an anagram (grind the letters ).
'inside'+'teams'='insideteams'
'insideteams' anagrammed gives 'DISSEMINATE'.
(Other definitions for disseminate that I've seen before include "Broadcast" , "Spread widely" , "Spread abroad" .)
