The Swiss still holds the record for the oldest top-ranked tennis player on the ATP list at 36 years and 320 days, and Djokovic will be in the top spot on April 8 at the age of 36 years and 322 days, surpassing his former rival.
Djokovic will remain in the top position until at least April 8, thanks primarily to Yannick Siner and Carlos Alcaraz, who withdrew from some tournaments in the past period.
The Serbian will make his next appearance at the Masters tournaments in Indian Wells and Miami, where he has not played for several years.
