Team's defending shot, ball for Brazilian maestro (5-5)

I believe the answer is:

villa-lobos

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

'brazilian maestro' is the definition.
The definition suggests a singular noun which matches the answer.

'team's defending shot ball' is the wordplay.
'team's' becomes 'villas' (Aston Villa FC).
'defending' is an insertion indicator (inserted letters are defended).
'shot' becomes 'lob' (type of shot in eg tennis).
'ball' becomes 'o' (O looks like a ball).
'lob'+'o'='lobo'
'villas' enclosing 'lobo' is 'VILLA-LOBOS'.

'for' is the link.

Can you help me to learn more?
