Novak Djokovic has kept fans guessing on his future after delivering an emotional runner's-up speech to the Australian Open crowd before later declaring he will keep pushing for another grand slam.
The superstar Serb was scintillating as he claimed the opening set of Sunday's final against world No.1 Carlos Alcaraz but was eventually overrun 2-6 6-2 6-3 7-5, falling short of a record 25th singles slam.
