Goffin, playing the ATP Finals for the second time, took command in the third set, serving for the match with a 14th ace of the match.

"I am really happy. It was such a good atmosphere tonight," Goffin said.

Nadal, who pulled out of he Paris Masters at the quarterfinals 10 days ago, had admitted before the match that his knee was "not perfect". His countryman Pablo Carreno Busta will take his place in Group Pete Sampras.

Nadal has won 75 tour-level titles, including 30 ATP World Tour Masters 1000 crowns but he has never won the ATP Finals. He qualified for the event 13 times but competed only in eight editions. 

"My season is finished," he said after the match. "I had the commitment with the event, with the city, with myself. I tried hard. I did the thing that I had to do to try to be ready to play. But I am really not ready to play."

"I tried, but (it) seriously was a miracle to be very close in the score during the match."
