Novak Djokovic will make his return to tennis in Abu Dhabi at December's World Tennis Championship.
The Serbian has skipped the back end of the current season because of an elbow injury, playing no part since abandoning his Wimbledon quarter-final against Tomas Berdych in July.
But 30-year-old Djokovic will return for the 2018 campaign, and the 12-time grand slam winner is planning an early start with an appearance at the December 28-30 exhibition tournament in the United Arab Emirates.
World number one Rory McIlroy pulled off his first professional hole in one on the 15th hole in the second round of the 2015 Abu Dhabi Golf Championship.
The Northern Irishman used a 9-iron from 177 yards and is just two shots off leader Martin Kaymer after day two.
A student asked the Prime Minister "what is your next step in Arab Spring countries?"
He replied: "I am a supporter of the Arab Spring". He said that all countries should be free to follow their own paths, but that he wanted to encourage the "building blocks of democracy" such as rule of law, women's rights and a free press.
One of the students has asked David Cameron why he supported an EU resolution that criticised the UAE for its human rights record.
The student asked why Britain is "putting pressure" on the UAE despite proclaiming that the countries share a strong relationship.
Mr Cameron commented that he was pleased to see that "more than three quarters" of the students in the room were women.
He also said that "nothing is off limits in the relationship we have" and that human rights would be part of their discussions.
The Prime Minister is about to hold a Q&A session with a group of students from Zayed University in Abu Dhabi.
The theme is expected to be about the Arab Spring and human rights.
