Club swam the Serpentine (4,3)

I think it could be either:

Which length description are you looking for?:

4,3

west ham

'club' is the definition.
(West Ham United football club)

'swam the serpentine' is the wordplay.
'serpentine' is an anagram indicator (a twisting or serpentine form of the letters).
'swam'+'the'='swamthe'
'swamthe' anagrammed gives 'WEST HAM'.

(Other definitions for west ham that I've seen before include "The Hammers F.C." , "London football side" , "East London football team" , "London FA team" , "The new stadium (anag)" .)

I've seen this clue in The Guardian.
