As reported here by on Monday afternoon, the former Adelaide United boss will take over from departed coach Branko Culina.

"John's record in the A-League is second to none and I'm confident that he's the right man to put Sydney FC where it belongs - at the top of Australian club football," said chairman Andrew Kemeny, despite only initially signing the coach until the end of the current campaign.

Kosmina will jump straight into the job, taking training at the Macquarie University Sports Fields tomorrow at 10am.

"There's enough quality in Sydney FC's squad to climb up the ladder and challenge for the A-League title this season," said Kosmina. "I'm tremendously excited to be back in the A-League with a club of Sydney FC's potential.

The former Socceroo assistant coach will face a baptism of fire in his first match, facing the table topping Central Coast Mariners at the SFS on Sunday afternoon.

However, Kosmina will have to coach Sydney from the stands for four more games. He still has to see out a five match touchline ban after comments made as Adelaide coach after the Preliminary Final win over Newcastle in February.
