Man's familiar following in the field of football (6)
I believe the answer is:
united
'familiar following in the field of football' is the definition.
I can't tell whether this defines the answer.
'man's' is the wordplay.
I cannot quite see how this works, but
'man' could be 'ted' (Ted is a man's name) and 'ted' is found within the answer.
The remaining letters 'uni' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for united that I've seen before include "Manchester _____, current Premiership champions with..." , "... we stand, divided we fall" , "Untied, being allied" , "Unified" , "Merged into one" .)
