Love Bruce's finale in The River (4)
I believe the answer is:
nile
'river' is the definition.
(I know that Nile is a river)
'love bruce's finale' is the wordplay.
'love' becomes 'nil' (love and nil mean zero in cricket and football).
'finale' suggests the final letters.
The final letter of 'bruce' is 'e'.
'nil'+'e'='NILE'
'in the' acts as a link.
(Other definitions for nile that I've seen before include "Egypt's river" , "Current" , "White or Blue river of Africa" , "River that's Blue and White" , "Egyptian river" .)
