Serbian tennis player Novak Djokovic has rivalled Roger Federer. The 33-year-old Serb is at the top of the world rankings for the 310th week.
Djokovic, winner of the Australian Open for the ninth time last month, passes the 39-year-old Swiss next week and then takes the record alone.
The Serbian is in his fifth period at the top of the world ranking. He was number 1 for the first time on July 4, 2011. Djokovic was then 24 years and 43 days old.
His longest streak at the top of the global ranking was between July 7, 2014, and November 6, 2016: 122 weeks in a row.
Djokovic was now number 1 since February 3 last year. He then relieved Rafael Nadal in the lead.
