After winning his second Wimbledon title, world number one Novak Djokovic is set to tie the knot in the tiny Adriatic republic of Montenegro.

Djokovic and longtime girlfriend Jelena Ristic are due to wed in the luxurious Adriatic resort of Sveti Stefan on Wednesday in a closed ceremony, local media reported.

A Djokovic family spokesperson on Tuesday said only that a statement would be sent to the media, without revealing any details.

The couple, who are expecting their first child later this year, reportedly wanted to have a private ceremony only with the closest friends and family present.

AFP reporters at the scene said Sveti Stefan, as well as the nearby upmarket Kraljicina beach – where the wedding banquet would be held – were closed off for public by discreet but efficient security, to prevent possible intruders or paparazzi.

Montenegrin media reported that Djokovic’s coaches Boris Becker and Marjan Vajda, as well as several tennis players – among them Maria Sharapova and Andy Murray – would attend the wedding.

Djokovic, 27, who dedicated his Wimbledon title to his future wife and a child, said he would “now close a tennis chapter for a while”.

“A lot of great moments are ahead of me: marriage, becoming a father in a few months… I am going to enjoy spending time with my family and my future wife,” Djokovic told reporters.
