Squanders money at Chelsea (5)
I believe the answer is:
blues
'chelsea' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for blues that I've seen before include "Oxbridge athletes" , "Conservatives" , "Gloom" , "Jazz classic (2,5,5) - See 9" , "Australian redheads" .)
