Novak Djokovic vowed to `continue fighting` for Grand Slam titles after his US Open semi-final exit to Carlos Alcaraz on Friday. Djokovic, whose dream of a record 25th Grand Slam title ended in a straight-sets loss to Alcaraz, pledged to keep playing next year. 

"I`m not giving up on Grand Slams, I`m going to continue fighting," the 38-year-old Serbian legend said after his 6-4, 7-6 (7/4), 6-2 defeat. "I still want to play a full Grand Slam season next year. They are just different from any other tournament. They are the pillars of our sport." Djokovic had warned before Friday`s semi-final he would need to be in peak physical condition to stand a chance of toppling the 22-year-old Alcaraz.

The Spaniard has dominated men`s tennis alongside Italian world number one Jannik Sinner in recent seasons, with the duo splitting the last seven Grand Slam tournaments between them. However, Djokovic said he had faded after running Alcaraz close in the opening two sets in Friday`s semi-final. "I ran out of gas after the second set," he said.
