The Danish superstar would have to win a couple of grand slams and become number one in the world which is certainly possible. He's already in the top 10 with a Masters trophy in the pocket however there is still work to be done. Wozniacki would certainly love to see it as she played tennis hoping to inspire many more to pick up the racquet and Rune is certainly among them.
The former Dniash player is actually in Paris for the Legends event and she and Rune ran into each other on the grounds of the complex with the meeting captured by cameras. They exchanged pleasantries which you can see below.
