Novak Djokovic has admitted he is unsure of how physically ready he will be for his US Open semi-final against Carlos Alcaraz but is determined to do all he can to give himself the best chance against the Spaniard when they face each other on Friday.
Djokovic reached the last four late on Tuesday night with a tremendous 6-3, 7-5, 3-6, 6-4 win against the fourth seed Taylor Fritz. Although Djokovic found himself under constant pressure in his service games and at times was outplayed by his American opponent, he showed his peerless mental toughness by saving his best level for the most important moments as he eked out a victory in four sets.
