One of four players, not a good one, in football club (4,3)
I believe the answer is:
west ham
'football club' is the definition.
'one of four players not a good one' is the wordplay.
'one of four players' becomes 'west' (bridge players are given names of compass points).
'not a good one' becomes 'ham' (I can't explain this - if you can you should believe this answer much more).
'west'+'ham'='WEST HAM'
'in' is the link.
Can you help me to learn more?
(Other definitions for west ham that I've seen before include "East London football team" , "The Hammers F.C." , "The new stadium (anag)" , "London FA team" , "London football side" .)
