Notorious kung-fu exponent playing a concertina (4,7)

I believe the answer is:

eric cantona

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

'notorious kung-fu exponent' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'playing a concertina' is the wordplay.
'playing' is an anagram indicator.
'a'+'concertina'='aconcertina'
'aconcertina' is an anagram of 'ERIC CANTONA'.

Can you help me to learn more?
