ATP Finals: Djokovic, Zverev set for championship clash

Novak Djokovic produced a masterclass to crush Kevin Anderson and set up a title decider at the ATP Finals against Alexander Zverev, who ousted Roger Federer after a bizarre incident involving a ball boy.

It will be the 18th time in ATP Finals history that two players who played each other in the round robin stage have played again in the final.

Novak Djokovic will look to equal Roger Federer's six ATP Finals titles when he takes on Alexander Zverev in Sunday’s final.

The Serb's five titles have come in Shanghai in 2008 followed by four straight victories in London from 2012 to 2015.

The World Number 1, the favourite for the title, has progressed to the final without dropping a set. No player since Ivan Lendl in 1986 has won the year-end finals without dropping a set.

In his path is World Number 5 Alexander Zverev, a three-time ATP World Tour Masters 1000 winner — at Rome and Canada last year and Madrid this year.

The 21-year-old German first played against Djokovic in Rome last year and defeated the then World Number 2. Since then, he has lost both of their meetings — in the semifinals of Shanghai a few weeks ago and in the round-robin stage of the ATP Finals.

ATP Head-to-head: Djokovic leads Zverev 2-1

Since the start of Wimbledon this year, Djokovic's record reads 35-2 and against top 10 players it is a formidable 10-0. It will be a formidable task for the youngster but he has been in good form in his run up to the final.

In ATP Finals history, round-robin stage opponents have clashed again in the final on 17 occasions, with the loser winning more than half the meetings -- nine times.

Zverev will be hoping for a repeat of the same in the 18th such meeting on Sunday.
