FEARS are growing that Harry Kewell will miss the World Cup after revelations the Socceroos star isn’t even fit enough to train alongside teammates at Turkish club side Galatasaray.The Australians already face an injury crisis with players such as Mark Bresciano and Vince Grella also battling for fitness ahead of the naming of the squad in 31 days’ time.In a major blow to Australia’s preparations for South Africa, a source close to Kewell told The Sun-Herald: ”There’s a good chance that Harry won’t make the World Cup. Things aren’t looking good for him.”He’s not been at [Galatasaray] training and originally they thought he’d be not just training but playing by now. Obviously they’ve only got five or six games left so if he misses those, he’d be looking at going into the World Cup with virtually no match practice for six months.”Kewell has been sidelined with a groin injury since December. The potential absence of the injury-prone striker – who has scored 13 goals in 45 appearances at international level – would leave a gaping hole up front for the Socceroos and would heap added pressure on Tim Cahill to find the back of the net.Socceroos coach Pim Verbeek has made it clear he is not prepared to carry players who are injured or short of match fitness. Last week Verbeek admitted he was ”worried” about the condition of Kewell and Bresciano.Football Federation Australia played down the latest concerns over Kewell’s fitness. ”We’re confident we have the medical experts and the systems set in place in Australia and overseas,” spokesman said. ”We’re constantly monitoring the health of all the potential Socceroos. At this stage there are a few niggling injuries but no major concerns.”Kewell will be monitored by Dr Peter Brukner, who said of the 30-year-old: ”He’s got one of those bodies that’s a little bit fragile.”
