World number one tennis star Novak Djokovic celebrated his US Open victory on Sunday by reenacting a scene with Gerard Butler from the actor's film 300.
The Serbian managed to claim his 10th Grand Slam title with a four-set victory over Roger Federer at Flushing Meadows in New York.
After the match, Djokovic told The Mirror that he and the Scotland-born Hollywood actor are "good friends" after meeting several years ago.
In a video uploaded to Twitter by Djokovic's wife Jelena, the tennis star and Butler yell the famous line, "this is Sparta!" to the camera.
