“That silly bugger Arnold has been saying he might leave him out and I say, you won't win if you do.

“You see, they can't win without Harry. He has something the rest don't,” Lee told au.fourfourtwo.com today today from his elite “IQ” coaching program in Sydney.

And Lee should know – he guided Kewell's junior career before he landed in England over a decade ago and is credited by the player himself as having a major influence on his formative years in the west of Sydney.

“Please your bloody self but he [Harry] makes the difference between winning and losing," added Lee, 70, who these days lives on the Central Coast.

The highly respected coach cites the 2001 World Cup qualiifers with Uruguay as a good example of Harry's worth to the side and in particular Mark Viduka, the Socceroo frontman likely to profit most from Kewell's wizardry in the forward line.

“Harry put in about ten crosses for that knucklehead Viduka who should've scored off them. Him [Kewell] and Muscat were the only two who played that day. The rest just wandered around."

And Lee still recalls Kewell's never-say-die attitude as a fresh faced kid from Smithfield.

“I remember Harry practically breaking legs as a kid to win a game when he was losing 1-0 with a few minutes to go.

“One thing for sure, Harry hates losing.”
