Former world number one Novak Djokovic and Switzerland’s Stan Wawrinka will return from lengthy injury breaks at the Mubadala World Tennis Championship (MWTC) exhibition event in Abu Dhabi in December.

After a poor run of form this year, Djokovic retired from his Wimbledon quarter-final against Czech Tomas Berdych in July, and the 30-year-old ended his season shortly afterwards due to a right elbow injury.

“The line-up is very strong as always, and it will be the perfect way to make my comeback and begin the season. Abu Dhabi is an amazing place, and this is going to be a great event for all of the fans,” Djokovic told the tournament website.

Three-time Grand Slam winner Wawrinka did not defend his US Open title this year, and announced the end of his season in August due to a knee injury.

“The fans are amazing there and the draw is as strong as always, with a lot of great players. My recovery is going well, and I can’t wait to be back on court,” Wawrinka said.

World number one Rafa Nadal, Austrian Dominic Thiem, Spain’s Pablo Carreno Busta and Canadian Milos Raonic will also compete in the tournament from December 28-30.
