In Netherlands notice American tennis star (5)
I believe the answer is:
nadal
'tennis star' is the definition.
The definition suggests an adjective which matches the answer.
'in netherlands notice american' is the wordplay.
'in' is an insertion indicator.
'netherlands' becomes 'nl'.
'notice' becomes 'ad'.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'ad'+'a'='ada'
'nl' placed around 'ada' is 'NADAL'.
Can you help me to learn more?
(Other definitions for nadal that I've seen before include "Star with a 30 [RACKET]" , "Rafael __, Spanish tennis player" , "court figure" , "tennis champion" , "Top tennis player" .)
