Spaniard no longer serving — nothing left (5)

I believe the answer is:

nadal

I'm a little stuck... Click here to teach me more about this clue!

'spaniard no longer' is the definition.
I can't judge whether this defines the answer.

'nothing left' is the wordplay.
'nothing' becomes 'nada' (synonyms).
'left' becomes 'l' (common abbreviation).
'nada'+'l'='NADAL'

'serving' acts as a link.

Can you help me to learn more?

(Other definitions for nadal that I've seen before include "Rafael __, Spanish tennis player" , "Star with a 30 [RACKET]" , "court figure" , "Top tennis player" , "tennis champion" .)

I've seen this clue in The Times.
