Novak Djokovic battled from a set down to beat Italian Lorenzo Musetti in the final of the Hellenic Championships in Athens and win the 101st title of his career.
The 24-time Grand Slam champion said he felt "proud" to come through a grueling three-hour encounter, eventually getting over the line 4-6 6-3 7-5.
Djokovic, 38, shared a long word with Musetti at the net after the second seed fell to a sixth consecutive defeat in finals and missed out on a place at the season-ending ATP Tour finals as a result.
