As a young kid growing up in Australia (I'm 25 now), I remember Kewell as a 17 year old when he scored in both legs against Iran in the '98 world cup qualifying play off. We failed to qualify on away goals but all of a sudden, a country where the vast majority couldn't give a rats about the round ball game, was talking about this kid.
He inspired (my generation at least) to play and watch the game, he went on to win the PFA young player of the year award in 2000 (to put it into perspective the 99 winner was Anelka and the 01 winner was Gerrard) and when he signed for Liverpool I was ecstatic! I know many a kid my age in Australia that started watching us due to him (having never been old enough to witness Craig Johnson).
Its a shame his injuries hampered his career and we never got to see his full potential; there were flashes now and then but 05/06 was his best for me. 06 FA Cup Semi Final vs Chelsea I felt was his best game for us, midfield of Gerrard - Sissoko - Alonso - Kewell was a treat.
Part of Australia's so called 'golden generation' (Schwarzer, Cahill, Viduka, Kewell) that inspired many in Aus!
