Juan Martin del Potro feels proud of his achievements. In a recent interview, the Argentinean player recalled his feelings after four wrist surgeries and his fear of having to end his career. 'I thought I would have not played anymore', del Potro admitted.

'I think that the worst is behind me. All of them have been historical achievements for me and unthinkable ones after my bad streak with injuries. Sometimes people tell me that it's like a film for all what I went through, for the bad moments I suffered, for getting closer to retire from tennis.

And then suddenly coming back.'. Del Potro feels proud about his comeback: 'What I gave for tennis and with tennis means everything. It's something amazing. I mentally try to be strong every day to be able to handle my body with head despite some pain.

With positive mentality so that it doesn't affect my game.' ALSO READ: Rafael Nadal could make important changes to his long-term schedule
