Sydney FC to replace ill Yairo Yau with Serbian midfielder Milos Dimitrijevic Yairo Yau is to leave Sydney to recover from illness in Panama. Sydney FC have cleared the way for the signing of Serbian midfielder Milos Dimitrijevic after it was revealed that winger Yairo Yau is to leave the club to recover from compartment syndrome. Yau departs immediately after the diagnosis of a condition where blood supply to a limb is restricted by swelling in the muscles, and which can be life or limb threatening. Though the club declined to reveal further details to respect Yau's privacy, it's believed to relate to a leg injury suffered earlier this season and has ruled him out for the rest of the season. The Panamanian's loan deal with Sydney has been cancelled, and it's likely he will return to San Miguelito in his homeland for treatment - though Sydney say they are not certain of his future plans. "This was the best decision for me and the club to allow me to recover from my injury," Yau said via a club statement. I wish all the best to the club and to the team and I hope they go on and make the A-League Finals. An erratic presence on the wing, Yau scored six goals in 27 games for the Sky Blues though was used largely off the bench since joining in July 2012. "Yairo has given great service to Sydney FC over the last 19 months and has become a firm fan favourite," said coach Frank Farina in the same statement. We wish him a speedy recovery and all the best for his future career. Once his departure is ratified opens the way for Dimitrijevic to sign a six-month deal, having already passed a medical and started training with the club. Having trialled on the recommendation of centre back Nikola Petkovic, the 27-year-old would complete a Serbian spine to the side behind striker Ranko Despotovic. Meanwhile, Western Sydney say they have been given no notification by marquee signing Shinji Ono that he intends to sign for Japanese club Consadole Sapporo. Japanese media reports on Tuesday said Ono had agreed a return to the J-2 club from June, once his Wanderers contract expires, but a Western Sydney spokesman said the club had heard nothing from the player about it. Sapporo had already made a bid to sign him in the January transfer window.
