ATP Finals will be played in London in 2018, 2019 and 2020 as well. But Novak Djokovic hopes that the venue and city will change by 2021. The tournament was first played in London in 2009 and it was a big success as every year, it welcomes more than 250,000 fans.

'The World Tour Finals in London have been a great success,' Djokovic admitted. 'No doubt why people are considering to keep it there. But I think we should change. We should take this tournament, which is the biggest event that the ATP World Tour has, we should promote it somewhere else.

We should allow other cities to have the opportunity to see the best eight players.' The likes of Djokovic, Roger Federer, Rafael Nadal, Andy Murray are all Europeans. If the venue of the tournament were changed to somewhere like South America or back here into the Far East after they have played in Paris Bercy (Paris Masters), would that present a problem? 'Well, right now the way the schedule is, you have a week between Paris and World Tour Finals, so I don't think it would be too much of a problem.

You would have time to get used to whatever conditions or surface you would have. You mentioned South America. I think anywhere in South America would be a huge success. There will be a lot of interest in the tournament, including America, that has a long tennis tradition.

Anywhere in Europe really. I mean, it's not like it works only in London or Paris or so forth. There are so many different markets, so many different cities around the world that want this tournament. Who wouldn't like to see the best eight, elite eight players in the world? Nothing against London.

In contrary, as I said before, it's an amazing success, amazing attendance. It speaks about the tradition of tennis that is nurtured in London because of Wimbledon because of the tennis tournaments that have been held there.

Tennis is one of the most famous sports in England for so long, over a hundred years. That's why it's a success there. That's why ATP is considering keeping it there. In my opinion ‑ I'm not the one who decides ‑ but I hope it moves somewhere else because it will be good for the sport.' ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
