Champions of the aristocracy (5-7)

I believe the answer is:

title-holders

I believe this clue is a double definition.

'champions' is the first definition.
('title-holder' can be a synonym of 'champion')

'the aristocracy' is the second definition.
(aristocracy often hold titles)

'of' is the link.

I've seen this clue in The Guardian.
