We finish with more tennis, and when South Africa's Kevin Anderson stunned the world by reaching the final of Wimbledon in 2018 and his performance inspired a new crop of players in his home country. In the Johannesburg suburb of Yeoville, a passionate coach who gives lessons for free tapped into this wave and established a grassroots tennis movement. CGTN's Sias du Plessis has more on Michael Nkosi's efforts to help kids and grow the sport.

There are many challenges facing the youth of South Africa, crime, drugs and poverty, but in the city centre of the City of Gold, one man is making a difference by teaching tennis to boys and girls with the hope that they can escape their circumstances and forge a future through sport.

MICHAEL NKOSI TENNIS COACH IN YEOVILLE "We are really having a challenge here with kids that grow up without mentors, without people that are looking up to them, role models, proper role models, not crime syndicates, not drug dealers and people who are pompous about doing crime but kids should look up to sports people as they are role models."

Michael Nkosi has been coaching kids for free since 2003 and says he derives his daily energy from their passion for tennis and the hope of making it as a professional player one day.

MICHAEL NKOSI TENNIS COACH IN YEOVILLE "I wouldn't be feeling as young as I am if it wasn't for the kids, they keep me alive every day. I have always told them that if you can't beat me at my age, forget about going anyway but I have got guys that drill me like nobody's business so I'm definitely expecting to see a champion here."

The 64-year-old is confident says that despite any support from local government, he can produce future champions from the streets of Yeoville.

MICHAEL NKOSI TENNIS COACH IN YEOVILLE "We definitely have to be excited about this place, this is where the future champion of Wimbledon will be coming out of, as I've said it, I know it is exactly as I have said it, the future champion will be coming out of here, whether somebody likes it or not, the future champion will be coming out of here."

SIAS DU PLESSIS JOHANNESBURG "As Michael Nkosi says in tennis, we are all champions, and it is champions like him that are making a difference in one of the most crime ridden parts of Johannesburg, changing lives by inspiring a group of young kids with very little hope with the promise that one day through the sport of tennis, they could one day realize a dream of playing in the finals of the most famous tournament in the world.
