Red Devils brought together? (6)

I believe the answer is:
united
'brought together?' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for united that I've seen before include "See 1" , "Joined together like Manchester soccer team" , "Got together" , "... we stand, divided we fall" , "Joined together as in alliance" .)
