Although he was voted the greatest ever Australian soccer player in 2012, the rest of the world was less impressed with a player heralded as a potential star.At the end of the 2002-03 season, Harry Kewell had the soccer world at his feet. The flying winger was expected to spurn the advances of AC Milan and Barcelona to join newly crowned Premier League champion Manchester United, and had been earmarked as a replacement for Ryan Giggs on the left flank at Old Trafford.
Fast-forward 11 years and Giggs is miraculously still putting in a shift for the Red Devils, albeit at a substantially reduced intensity and with some coaching duties thrown in.
His onetime supposed successor, meanwhile, called time on his playing career in front of a packed press conference at Melbourne's AAMI Park on Wednesday, at age 35.
He had already become the youngest Socceroo in history before entering the world's spotlight at Leeds. And during the last decade Kewell has continued to write himself into Australian soccer history, with moments like the goal against Croatia at the 2006 World Cup, or the equally dramatic red card against Ghana four years later, with plenty of other highs and lows thrown in before, during and after those landmark events.
But the sad truth is that outside these shores, Kewell may as well have hung up his boots the day he left Leeds in 2003.
The succession of injuries that plagued his career meant — to a global audience — the most promising player ever produced by Australia never lived up to that billing.
Instead, throughout five years at Liverpool, three at Galatasaray and a nomadic existence thereafter, the appearances became less and less frequent and his pace largely dried up, robbing him of his explosive acceleration and forcing him to become a different type of player.
There is no doubt he remained supremely talented, and still produced occasional flashes of game-changing brilliance. But they happened away from the main stage. When chances to stamp his mark on a major occasion arrived, his body denied him a chance to seize it, most notably in the 2005 Champions League and 2006 FA Cup finals.
Every Australian soccer fan has their favorite Kewell moment. Unfortunately, for most people elsewhere in the world, the most enduring image is of him limping off at the Atatürk Stadium in Istanbul, with an uncharacteristic consoling arm offered by Liverpool manager Rafael Benitez.
Let's get you a nice ice pack | Rafa proves he's capable of putting an arm around the shoulder.
He was subbed off with a torn abductor muscle 28 minutes into the biggest match of his club career. Twelve months later it happened again, a torn groin forcing him off at the Millennium Stadium 48 minutes into the game against West Ham.
Worse still, these were two of the best finals in the modern history of the respective competitions. Both were settled on penalties after 3-3 draws, and each time the Australian was already on the treatment table, the prospect of another long spell on the sidelines ahead.
Make no mistake, this is Kewell's legacy to the soccer world, outside Australia. The player himself acknowledged it this week, when asked if he felt in anyway unfulfilled upon hanging up his boots.
"I do sit there with my wife and my close friends and wonder, what if? I wonder if I didn't have those injuries, what could have been?"
We'll never know now. Australian supporters can console themselves with Kewell's star turns in green and gold down the years, while Liverpool, Galatasaray and even some Leeds fans, those not alienated by his defection to the Turkish club, will have some fond memories.
But for the neutrals, the question is the same as that which may nag at Kewell in the recesses of his retired mind. What could have been?
