Certainly, Great Pancho didnīt have the menthal issue fed has with Nadal, he just didnīt have too many menthal issues to worry about.I conīt know if he was superior to others from that point of view, but he certainly deserves to be respected as a man of great nerve and courage.
From everything I have read, Pancho was the mentally toughest competitor in tennis history. Jimmy Connors said that if he had to choose one player to play for his life, it would be Pancho. Jimmy also said that watching Pancho play was like looking into a burning flame. Pancho's desire to win was greater than the others. He was much tougher than Federer. Pancho was also much tougher than nadal. Even Nadal admitted to having mental issues against Djokovic last year. Pancho had no mental issues against anyone.
