In an interview to Golpe de Tenis, the former player Diego Hartfield recalled his 2006 French Open loss to Roger Federer. Hartfield said: "It's a great memory to have played with Federer, clearly. It surprises me a lot that he is still there.
In 2006 when I faced him, he was already a kind of superhero and now he keeps being so successful and winning something I had never imagined. It's a very nice memory, it's a pleasure to have faced him and that everyone remembers it.
It's a great satisfaction for me to have faced him: I was playing very well these weeks, I had won two Challengers and that match was the crown of a very nice time for me. He must have been surprised too because he did not know me and I was playing very well."
On how he felt after his retirement from tennis, Hartfield added: "In my case, I did not feel an emptiness. There are many things of tennis I liked but not the other parts of a tennis player's life, that's why I ended up retiring pretty young, besides being injured.
I also liked a lot the idea of living in a settled place, that's why I retired being pretty young. There are many things you miss: kids, tournaments, clubs and many beautiful places where you play. It depends a lot on a player's lifestyle.
It's not the same thing to be in an ATP tournament as a world No. 100 than playing Futures or Challengers, those are two totally different things."
