Egypt's Mohamed Elshorbagy has retained his place at the top of the Professional Squash Association (PSA) men's world rankings for an eighth successive month, equalling the record of rival Ramy Ashour.
Elshorbagy has now topped the rankings for an eighth successive month and 21 months overall - equalling the time that fellow Egyptian Ashour topped the rankings between 2010 and 2013.
The rivalry between Elshorbagy and Ashour has dominated the PSA World Tour in recent years, with their World Championship final in 2014 labelled as one of the greatest matches of all time.
Elshorbagy, crowned this year's British Open champion, broke Ashour’s record for the highest ever points average in April and will look to surpass the three-time world champion once more next month.
The top 10 is mostly made up of Egyptians with six included in total.
Omar Mosaad is at number three, Elshorbagy’s brother Marwan lies at number six and Karim Abdel Gawad, Ali Farag and Tarek Momen hold positions eight, nine and ten respectively.
World champion Gregory Gaultier stays at number two and England’s Nick Matthew remains at number four.
Colombia’s Miguel Angel Rodriguez and Frenchman Mathieu Castagnet are the other non-Egyptians in the top 10, and have respective rankings of number five and number seven.
Elsewhere, Ashour maintains his number 12 ranking, while English duo James Willstrop and Daryl Selby feature at respective positions 19 and 20.
