Remember when Guga always had that smile on his face! He loved the game. But, the smile seemed to fade toward the end of his career, possibly because of hip pain. It is also possible that, because of his hip, Guga never really realized his peak. Are you aware of any interviews or discussions about when he started having trouble with the hip? I do agree that Guga vs. Nadal on clay would be an epic match-up.
How I would have loved to have seen a match between Guga at his peak, and Nadal.
