El Aynaoui reached World No.14 back in 2003 at the age of 32 and he faced Andy Roddick in an iconic match that year at the Australian Open which lasted a shade under five hours and was won in the final set by Roddick 21-19.
Speaking to Punto de Break, he says he picks Nadal over Djokovic due to his temperament on the court and how he manages defeat instead of doing 'strange' things on the court like Djokovic and he says it is more about that than stats or numbers in his eyes.

"For me it's not all about tennis and numbers, you also have to look at how the person is and how they manage defeats. In that sense, Nadal is number one, we never saw him do anything strange on the court, and I don't say it because he is Spanish," he said to Punto de Break.
"He never broke a racket, nor did we see him complain about anything or throw/tank a match, he has always shown a good attitude, he is an example for everyone who plays tennis. We will probably never see players like Federer or Nadal again. There is something else beyond the numbers, that is seen in the difficult moments of life, in how one behaves.
"When you win it's very easy, everyone is with you, but the real champion is seen in defeat. Rafa and Roger have always accepted the defeats better than Djokovic, maybe that is why he has won more than them. But not everything is about the on-court numbers, above that is the person themselves."
