I like to see that more and more supporters are welcome in the stadiums. It is unbelievable that a number of people have not yet been vaccinated. They ruin it for the rest, even at sports competitions. Would they also work with access test there? Or would you be welcome at tennis matches with a vaccination certificate?
I haven't read much about that, how those things go. For the players in tennis it doesn't matter much, public or no public. For inexperienced players it can be an advantage if there is no audience, as it could certainly bring a certain pressure in the beginning. That differs per player.
