Zverev beat the top two players in consecutive matches to earn his second title at the ATP Finals.

His more aggressive tactics paid off handsomely against Daniil Medvedev in a in a dominant 6-4 6-4 victory - in which he did not face a single break point.

"It was definitely a game plan," Zverev said.

"He's one of the best baseline players in the world, and against him you need to take control over the points, and I did that today and that's why it worked out very well for me."

A day after beating world No.1 Novak Djokovic over three sets in the semi-finals, Zverev raised his game to a new dimension.

It was a similar approach to how Djokovic beat Medvedev in the Paris Masters final earlier this month, when the Serb attacked the net more often than usual.

Medvedev, the US Open champion, won this event last year and had beaten Zverev five consecutive times - but was thoroughly outplayed on Sunday.

"There's no better way to end the season than winning here," Zverev said.

"I'm also now very much looking forward to next year already."

A sixth title in 2021 culminates quite a year for Zverev, who also won the gold medal at the Tokyo Olympics and had more wins on the tour - 59, one more than Medvedev - than anyone else.

The main thing missing in Zverev's trophy collection is a grand slam title.

"I kind of succeeded on every level and there's one thing missing," Zverev said.

"So I hope I can do that next year."

Medvedev said that Zverev "is capable of beating anybody" but that was no guarantee of major success.

While Medvedev won their group match in three sets, the final went Zverev's way from the start as he broek serve in the third game.

Helped by fast conditions inside the Pala Alpitour, Zverev was virtually untouchable on his serve, winning 20 of 25 service points in the first set.

He broke again in the opening game of the second set and hardly wavered the rest of the way.

This marked the first edition of the season-ending event for the top eight players in Turin - after 12 years in London, where Zverev won his first finals title in 2018.

"Obviously London was an incredible event but I think ... Italy has topped it," Zverev said.

Meanwhile, Pierre-Hugues Herbert and Nicolas Mahut won the doubles title by beating Rajeev Ram and Joe Salisbury 6-4 7-6 (7-0).
