Carlos Alcaraz shocked with Rafael Nadal's retirement decision

Revealing that Nadal's decision came as a shock, Alcaraz said, "Well, it was, honestly, I couldn't believe it when I watch it. You know, it didn’t affect me at all before the match. I didn't get distracted at all, I was just really focused on the match, I didn't think about Rafa's news. But obviously when I watched it, it was tough to accept it. I was in shock a little bit. Thanks that I saw it like one hour before the match, so I had time to accept it and forget it a little bit before the match."

Nadal's final tournament will be the Davis Cup finals this November in Malaga, where Spain take on Netherlands in the quarter-finals. It will be his first appearance since the Paris Olympics, and will also mark an end to a legendary career.
