Serena Williams will take on her sister Venus on the opening day of the Mubadala World Tennis Championship in Abu Dhabi on 27 December.

Serena Williams said: “I loved playing in Abu Dhabi last year. I am excited to return to such a beautiful city and to see my fans.
“This time, I’ll be playing against my sister, so the match will be even more special.”
