Italian football manager during final leg, riled (7)

I believe the answer is:

allegri

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

'italian football manager' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'during final leg riled' is the wordplay.
'during' says the answer is hidden in the clue.
'ALLEGRI' is hidden within 'final leg riled'.

Can you help me to learn more?

(Another definition for allegri that I've seen is " composer".)
