Swiss Roger Federer called the favorites of the upcoming Australian Open. “There is no doubt that Novak is the favorite. Regardless of what happened in Doha, he demonstrates a very powerful game of the last five to six months. Given his class, once he finds his tennis, it will be very difficult to beat him. As for me, I enter the Top 10 favorites. I don’t know the net, I don’t know my rival in the first round, I don’t know my day to start the tournament, ”Federer quoted Sky Sports as saying.
