Zverev has won three ATP Masters titles (Rome, Madrid and Montreal), but London marks a new era in his career, as he sets his sights on winning his first Grand Slam title in 2019.

The 21-year-old outclassed the world No. 1-ranked Djokovic, just days after losing to him in the group stage.

Djokovic even commented on Zverev's improved game, saying "You definitely played much better than you did the group stage...You deserved to win."

Some remarkable stats for Zverev include:

1

First player ever to beat both Roger Federer and Djokovic in the ATP Finals.

2

Youngest ATP Finals champion since Djokovic himself in 2008.

3

First German champion since Boris Becker in 1995.

4

Fourth player ever to beat Federer in a semifinal and Djokovic in a final of the same tournament.

Zverev is ranked No. 4, just 35 points behind Federer.
