“One of my biggest goals will be Roland Garros, but that goal is still far away. We've seen that all players have struggled throughout their careers, but I wouldn't call this 'fatigue' yet; I've only lost a couple of matches. I also have to remember what I've done in the last three years, where I've won a lot of matches and lost very few.”
