BELGRADE, (Reuters) – World number one Novak Djokovic is looking forward to returning to action in front of fans at the Serb’s charity tennis tournament in Belgrade this weekend.

The first leg of Djokovic’s Adria Tour is being held at his tennis complex by the Danube River, with Germany’s Alexander Zverev, Austrian Dominic Thiem and Bulgarian Grigor Dimitrov arriving for the event.

Fans will be able to attend despite the COVID-19 pandemic after the government lifted its ban on outdoor public gatherings.

“We have different circumstances and measures (to other countries) so it’s very difficult to think of international standards (regarding the pandemic),” Djokovic told a news conference.

Several thousand fans are expected to throng the makeshift stands at Djokovic’s complex over the weekend and Thiem said he was delighted to be part of the event.
