Well, yeah, the story has kinda caught my attention, although I don't know the ins and outs of it.
Djokovic is right: nobody should be forced to have the vaccine.
But I also agree with you - foreigners wanna stay in another country? Then abide by that country's rules.
It'll be a shame if he is deported, a shame for tennis. Djokovic will probably end up with most grand slams out of him, Federer and Nadal.
