Sydney FC aren’t waiting until the end of the season to lock down Milos Ninkovic for another year, with the club already entering talks to re-sign the veteran playmaker.

He might be in the twilight of his career but Ninkovic, 35, has shown no signs of slowing down and has already flagged his intention to continue playing for another year at least. The former Serbia international's contract does not expire until May, but Sydney FC want to make sure he is at the club next season.

Club sources told the Herald they had begun working on a new deal for Ninkovic, an unusual step so early in the season. The stringent A-League salary cap means clubs usually leave contract renewals until late in the season, to account for form and fitness.

The former Dynamo Kiev, Evian and Red Star Belgrade man has been one of the brightest performers in the Sky Blues’ title defence, netting twice in their first six games. His latest strike came on Saturday night, scoring the third goal in the club's 3-1 away win over Perth Glory in a grand final replay.
