Joined the team (6)
I believe the answer is:
united
I believe this clue is a double definition.
'joined' is the first definition.
('unite' can be a synonym of 'join')
'team' is the second definition.
(name of many soccer teams)
'the' acts as a link.
(Other definitions for united that I've seen before include "Joined together like Manchester soccer team" , "Joined into a single entity" , "See 10" , "See 14" , "cooperative" .)
