Wingers for Cowdenbeath - alternatively a London club (7)
I believe the answer is:
chelsea
'london club' is the definition.
(I've seen this before)
'wingers for cowdenbeath alternatively a' is the wordplay.
I cannot really understand how this works, but
'alternatively' could be 'else' (I've seen this before) and 'else' is found in the answer.
'a' is present in the answer.
The remaining letters 'ch' 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 chelsea that I've seen before include "Blue pensioner footballers" , "London Blues" , "Part of Manhattan" , "issue for Clintons" , "Lace she found in London area" .)
