Team boasted (4)
I believe the answer is:
crew
I believe this clue is a double definition.
'team' is the first definition.
(crew is a kind of team)
'boasted' is the second definition.
('crew' is past tense of 'crow', meaning to boast)
(Other definitions for crew that I've seen before include "Ship's company - bragged" , "Boat's workers" , "clapped themselves?" , "group of sportsmen" , "Sailors -- boasted" .)
