'progressive' is the definition.
Both the definition and answer are adjectives.
Maybe you can see an association between them that I can't see?

'striker fine leader' is the wordplay.
'striker' becomes 'forward' (both can mean an attacking player in football).
'fine' becomes 'thin' (similar in meaning).
'leader' becomes 'king' (a king is a royal leader).
'forward'+'thin'+'king'='FORWARD-THINKING'
