Fastest footballer George seizing chance (8)

I believe the answer is:

briskest

'fastest' is the definition.
(brisk can mean fast or energetic)

'footballer george seizing chance' is the wordplay.
'footballer george' becomes 'Best' (George Best was a footballer).
'seizing' means one lot of letters goes inside another (inserted letters are seized).
'chance' becomes 'risk' (synonyms).
'best' going around 'risk' is 'BRISKEST'.

I've seen this clue in The Times.
