Novak Djokovic has equalled Roger Federer's record of 310 weeks ranked as world number one.
Djokovic won his 18th Grand Slam title and his ninth Australian Open crown in Melbourne last month.
"After achieving the historic number one for the longest weeks at number one, it's going to be a relief for me because I'm going to focus all my attention on slams mostly," he said.
His victory in Melbourne takes him to two wins behind the joint holders of the men's Grand Slam record, Federer and Rafael Nadal.
Djokovic has been helped by temporary changes to the ranking system because of the coronavirus pandemic which means players can currently count tournaments from two years instead of one.
