Number 1 seeded player Michael Kouame from France has gone viral for all the wrong reasons after slapping his opponent Raphael Nii Ankrah in a shocking display of bad sportsmanship.
Kouame lost his match in the ITF juniors world tour.
The 15-year-old can be seen walking up the net and after shaking hands with his right hand he slaps his opponent with his left.
It is not clear why Kouame attacked his opponent but the incident sparked an on-court brawl.
