Coach taking on international scorer (6)

I believe the answer is:

busoni

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

'scorer' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?

'coach taking on international' is the wordplay.
'coach' becomes 'bus' ('bus' can be a synonym of 'coach'**).
'taking' says to put letters next to each other.
'international' becomes 'i' (abbreviation eg in IMF).
'bus'+'on'+'i'='BUSONI'

Can you help me to learn more?
