One person supervising journalists in team? (6)
I believe the answer is:
united
'journalists in team?' is the definition.
'United' can be an answer for 'team?' (name of many soccer teams). I am not sure about the 'journalists in' bit.
'one person supervising' is the wordplay.
'one' becomes 'unit' ('unit' can be a synonym of 'one').
'person supervising' becomes 'ed' (I am not sure about this - if you are sure you should believe this answer much more).
'unit'+'ed'='UNITED'
Can you help me to learn more?
(Other definitions for united that I've seen before include "Joined together, allied" , "Joined in marriage" , "Untied, being allied" , "Joined together -- in duet (anag)" , "See 9" .)
