Winning man promises to pay (10)

I believe the answer is:

victorious

'winning' is the definition.
(I've seen this before)

'man promises to pay' is the wordplay.
'man' becomes 'victor' (**).
'promises to pay' becomes 'ious' (more than one iou).
'victor'+'ious'='VICTORIOUS'

(Other definitions for victorious that I've seen before include "winning" , "Triumphant" .)

I've seen this clue in The Telegraph.
