Nick Kyrgios and Novak Djokovic are two of the tennis world's most outspoken profiles, but in recent years they have rarely had the same opinion.

What was required to unite them was apparently the vaccine requirement for participation in the grand slam tournament Australian Open.

Kyrgios, who is fully vaccinated, called the claim "morally wrong".

Djokovic has not revealed whether he has been vaccinated or not and has opened up not to participate in the Australian Open.

- This time I have to agree with him that free choice is important for everyone, whether it concerns me or someone else, says the 34-year-old Djokovic and continues:

- It really does not matter if it is about vaccination or something else in life.

You should be free to choose what you want to do.

In this specific case, what you want in your body.
