While the 34-year-old world number three is still planning a full 2016 schedule highlighted by his fifth Olympic Games in Rio, the two-time Rotterdam champion confessed: "At this moment I have no plans to stop, and I hope to return after 2016 in Rotterdam. But certainly at my age may there may come a time when it's over." The winner of 87 career titles including the all-time record of 17 grand slam singles crowns added that he does not fear the day when he will have to finally hang up his racquet.
