After the loss, Rafa said:

I think he’s playing great. He’s playing with a lot of energy, aggressive, determination. So well done for him. I honestly didn’t play a bad match, no, no. My attitude was great, I think, during the whole match. Good, positive, fighting spirit all the time, giving me more chances. That’s what I tried, no?

Don’t give up in no one moment during the whole match. I give myself an opportunity until the last point. Happy for that because my level of concentration and tennis was better, I think even the concentration than the tennis. But the tennis was not bad at all. It was difficult to play against him.

When the ball was new for me, have been better, honestly. Honestly, I had two breaks with new balls. Then I felt more comfortable with the new balls.

The ball became so heavy. He’s younger, he’s very quick. With these heavy balls, it’s difficult to produce sometimes winners. He has a lot of power, so he’s able to produce these amazing shots from a very difficult position. Nothing to say. Of course, I am sad. I lost an opportunity to be in the semifinals of another Grand Slam. But I lost against a great opponent. And he deserve it, too. Well done for him.

Our champ could lose his place at No. 1 in the FedEx ATP Rankings on 3 February should Novak Djokovic go on to capture his eighth Australian Open crown.
