Alex Corretja believes that talking about the greatest of all time in tennis is very good for the sport so he did his part in promoting the sport by sharing what he thinks of it.
There will never be a proper response in tennis as to who the greatest tennis player of all time is. It's a very subjective question similar to the best book or the best song ever. Fans of each potential GOAT will claims that their favourite is better than the other two. It would have been much simpler if only one player achieved so many great things but alas here we are.
Alex Corretja doesn't have a favourite in this race but he does think that talking about it is very good for the sport. He explained:
"It’s almost impossible to understand, but I’m very happy for Novak. It has been a difficult year. He is past Roger and is chasing Rafa again, so the race is still there. I think it is very interesting for the sport in general. It's good that Novak keeps on winning because he is such a professional player. I cannot even believe it."
Corretja further added:
"We all thought Pete Sampras’ 14 Grand Slams were never going to be reached. They went over that with 20, and now, again, Novak is chasing Rafa. I think it is interesting while both are healthy; we are waiting for Roger, of course."
