Djokovic joins a stellar field; which includes his fellow Big Three member Roger Federer, who is the reigning champion.
Tsitsipas last year reached the final in Dubai losing out to the Swiss ace; he will aim to go one better.
2018 champion Roberto Bautista Agut is also among the line-up; as is Gael Monfils, Fabio Fognini and Karen Khachanov in what will be an intriguing tournament with some of the World's best involved.
“We are thrilled to welcome Novak Djokovic back to the Dubai Duty Free Tennis Championships,” said Colm McLoughlin, Executive Vice-Chairman and CEO of Dubai Duty Free.
“He is one of the greatest champions the game has ever seen, with 16 Grand Slam titles so far to his name with no doubt more to come. We are delighted to not only welcome him, but also welcome one of the finest athletes in any sport over the past decade and more, Roger Federer, as well as one of the brightest future stars on the ATP Tour, Stefanos Tsitsipas.
“They will begin as favourites for the title, but experience over the years has shown us that none can be assured of success here in what is such a competitive field. It will be fascinating to see who will emerge as the winner.”
