Djokovic, however, is nigh native speaker fluent in English. It's superb.
Not only that, but Djokovic speaks 12 languages.
Nadal or alcazar can barely speak their own mother tongue.
So, before you come to me about on court behaviour and that being a marker of goat ness - consider the off court presence first.
Nadal never a GOAT. And let's not even talk about his doping.
Sidis, one of the most intelligent humans ever, spoke eight languages fluently and even created an entirely new language. That by the time he was eight years old. As an adult, he spoke over 40 languages fluently.
