Amateur player from insanely rich nation (10)

I believe the answer is:

corinthian

'amateur player' is the definition.
(Corinthian FC was an amateur football club)

'insanely rich nation' is the wordplay.
'insanely' is an anagram indicator.
'rich'+'nation'='richnation'
'richnation' is an anagram of 'CORINTHIAN'.

'from' is the link.

(Another definition for corinthian that I've seen is " Recipient of Paul's letter".)

I've seen this clue in The Telegraph.
