Sydney FC signs Serbian striker Ranko Despotovic Serbian striker Ranko Despotovic (L) has signed with Sydney FC until the end of the season. Sydney FC have moved to end their striking woes by signing Serbian international Ranko Despotovic. The 30-year old has signed with the Sky Blues until the end of the season but won't be available for Saturday night's match against Melbourne Victory. Instead, Despotovic will arrive on either Wednesday or Thursday next week and could be available for the Friday night away match against Melbourne Heart. However, it is more likely he will make his debut for the Sky Blues in the home match against Wellington Phoenix on November 23. Capped four times by his country, Despotovic arrives with an eye-catching resume that includes stints with Romanian giants Rapid Bucharest and arguably Asia's biggest club, Urawa Red Diamonds. However, his most profitable time was in Spain, where he chalked up a respectable goal-scoring record with three second division clubs - Murcia, Salamanca and Girona, the latter of whom he scored 18 in 34 games in 2010-11. Until now, the Sky Blues never quite managed to replace the departed Joel Griffiths, who took on a big-money move to China during the off-season. Fellow striker Corey Gameiro has also been sidelined with a shoulder injury. After leaving Japan earlier this year, Despotovic returned to his homeland to get his fitness in order before finding a new club. I'm very excited at the prospect of joining Sydney FC. I've been training regularly in Serbia and I'm looking forward to getting started," he said. I've played against the Socceroos [in 2011] and heard a lot about the A-League and what a good competition it is. I've also spoken to Nikola [Petkovic] and heard excellent things about Sydney FC and the direction the club is headed. Coach Frank Farina said he was pleased to sign a striker who he believes can make an instant impact. "We are very happy to be able to add another quality striker to our squad," he said. Ranko has a good pedigree, he can score goals and his height will give us a different attacking option. He will also add some extra experience to our front line. Victorian Premier League golden boot winner Milos Lujic had been training with Sydney but is now unlikely to be offered a contract after Despotovic's signing. Meanwhile, FFA officials are confident Socceroos striker Tim Cahill will be fit for the first match of Ange Postecoglou's reign despite reports of injury. Cahill visibly tired at the end of extra time as his MLS side, New York Red Bulls, fell victim to Houston Dynamo in the eastern conference semi-finals. It was rumoured Cahill's participation for the match against Costa Rica at Allianz Stadium on November 19 was in doubt. However, FFA officials confirmed they had been in contact with Cahill and insisted they were still expecting him to arrive in Australia early next week. It is believed he suffered from a severe bout of cramps rather than a soft-tissue injury as first feared.
