In an interview to El Pais the six-time Major winner Boris Becker commented on Novak Djokovic's arm injury that is influencing his US Open matches. The German said: "I do not think there is just a Grand Slam winner that won some tournament without feeling pain or some injury.
There are always some struggles, even if some players show it more than others and someone speaks more than others. There are more training sessions and you play more matches. Now rules are like this. I know Novak very well and when I coached him, he was never at 100 percent in the final on Sundays.
If you ask me if it's a serious injury that can make him retire I would say not, but if I have to say that it hurts him, I say yes." The 1988 tournament champion Mats Wilander said: "It's difficult to compare what we did in our cases.
The mentality is different. In the 80s we did not play thinking about this kind of things. If you played, you played. And we also won Grand Slam titles without being at our best. With Novak, I think he won Majors workout being at his best, so he can do it again."
