Sydney FC are set to retain the services of two of their biggest names with Brazilian striker Bobo and Serbian playmaker Milos Ninkovic on the cusp of signing contract extensions.

Sharpshooter: Bobo has been rewarded for his rich vein of scoring form.

Fairfax Media understands the club is confident of retaining the services of the two attacking stars after reaching an agreement in principle for new deals for both. Both marquees are coming off contract at the end of the season but are close to securing their future with the Sky Blues having agreed in principle to new deals that will be formally concluded in the coming weeks.

Sydney FC are set to hand Ninkovic a multi-year marquee deal that will could see the 33-year-old finish his playing career at Moore Park. The former Serbia international has submitted his paper work to become an Australian citizen and is expected to be nationalised before the start of next season, meaning he will not count as a foreign player for the club's A-League squad. The retention of Ninkovic is set to free-up a vital visa-spot on Sydney's roster for next season with the FFA reducing the limit of five positions to four and one reserved specifically for an Asian player.
