SYDNEY (Reuters) - Roger Federer is unlikely to play in next year's Australian Open but is still determined to make a return to tournament tennis at some stage, according to his coach Ivan Ljubicic.

The 20-times Grand Slam champion has been inactive since losing in the Wimbledon quarter-finals in July and undergoing another round of knee surgery.
