United team is ahead, by the sound of it (5)
I believe the answer is:
leeds
'united team' is the definition.
'leeds' can be an answer for 'team' (I've seen this before). I'm not certain of the 'united' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for leeds that I've seen before include "Industrial city of northern England" , "City of northern England - castle of southern England" , "Soccer team" , "Yorks city" , "English city" .)
