Stefanos Tsitsipas came from a set down to beat Dominic Thiem on a thrilling final-set tie-break and become the youngest winner of the ATP Finals in 18 years.

He won 6-7 (6-8) 6-2 7-6 (7-4) to claim the biggest title of his fledgling career.

Thiem, 26, who edged a tight first set, fell away in the second and the start of the third before fighting back.

But Tsitsipas forced a tie-break, and then won it.

He collapsed to the floor after Thiem put a forehand return out on the first match point before the pair embraced at the end of a two-hour 35-minute battle, with the Greek kissing his beaten opponent on the shoulder.

Tsitsipas is the youngest winner of the season-ending championships since Australia's Lleyton Hewitt in 2001 and claims prize money of just over £2m.
