In fact, this is the first time either man has ever qualified for the tournament, which sees the world’s top eight players come together at the end of the ATP season.
Goffin did play in last year’s event but only as an alternate, replacing injured Frenchman Gael Monfils and suffering a heavy defeat at the hands of Novak Djokovic.
Dimitrov meawhile, once a junior world No 1, is set to finish inside the top 10 for the first time with his run to the final propelling him to No 3 in the world.
