El Sherbini had not competed since winning the women's singles title at the World Championships in Chicago in March because of a knee injury.

Despite this, the 23-year-old eased past Rachael Chadwick of England 11-6, 11-5, 11-4 in front of the Giza Pyramids.

"I was really excited about today’s match and I just wanted to get on court and see how it goes, but it went really well," El Sherbini said.

"I was playing good and I’m really happy to be back.

"In the first game my knee was in my head a little bit, but I was running ok and it felt good. 

"I didn’t have any problems and hopefully it is going to be like this the whole week."
