Alexander Zverev claimed one of most significant wins of his fledgling career as he beat Roger Federer to reach the ATP Finals title match but became an unwitting pantomime villain in freakish scenes at the 02 Arena on Saturday.
The 21-year-old continued to dominate in the second and sealed a memorable victory as Djokovic faltered.
"So I'm happy he now has Ivan Lendl as a coach because Ivan, who won eight Grand Slam titles, can tell him the same stories I can tell him and brings an understanding of the game to his team", Becker said.
Zverev, who has won 10 tour-level titles, including a couple of Masters 1000 tournaments, came out all guns blazing in the final against Djokovic, a day after beating world number three Roger Federer in straight sets in the semi-final.
The 21-year-old has been long tipped to be the next big name in tennis but has so far struggled to weaken the grip that Djokovic, Federer and Rafael Nadal have on the game.
"You deserved to win and well done", Djokovic told Zverev.
The incident occurred in the decisive second set tie-break and forced a crucial point to be re-played. "The ball boy dropped the ball, so it's in the rules that we have to replay the point. I'm very sorry that this happened I didn't mean to upset anybody - that's all I can say, sorry".
"He apologised to me at the net".
"There's a lot of similarities in terms of trajectory.in our careers", said Djokovic, who ended a two-year Grand Slam title drought by winning Wimbledon this year, before going on to claim his 14th major trophy at the U.S. Open.
Zverev pockets $2,509,000 and 1,300 ATP Ranking points to finish the year as world No 4. "It disturbed Sascha", Djokovic said. "He's barely lost a match in the last six months", Zverev said. "You play against the best players only".
More than just the title, the way he overcame those world-leading players is likely to be a source of huge confidence for the German as he looks to improve his Grand Slam record in 2019.
"We (Djokovic and Zverev) had so many talks, not only about tennis but all different types of subjects - I won't mention what - but you are a sharing person and you have shared some titles with me".
To come back after a hard start to the year and an injury to win Wimbledon and the US Open this year, and become the dominant player in the second half of the year, speaks volumes for his mentality and love for the game. If we put things in perspective, it was an wonderful year, a great comeback so thanks for helping me get to where I am.
