Shortly after the loss of German # Alexander_Ziverev in front of Zhong Hyun at this year's Australian Open #, promising players received wise words from # Roger_Fider.
No matter what Federer said, these words seemed to have a positive impact, because at the end of the year he was the most successful player in this season's league match with 56 wins.
The 21-year-old has won three titles, including the Madrid Masters, and will be the first German player in 15 years to appear in the men's tennis final.
But he will have a date with Federer, who has 20 Grand Slam titles, and is looking to win the title for the seventh time.
The world number five, who trained with a Grand Slam title of 8 titles, did not mention that Federer's words of wisdom were behind his development, but he clearly did not hurt him.
"I was very disappointed with my defeat in the third round," Zverev told reporters after a 7-6 (6-3) win over John Esner to secure the semi-finals.
"He talked more about it and I shouldn't feel too frustrated," he said, "He came to the quarter-finals after his career period too."
Zverev appears to be a candidate for tennis leadership after the end of the current adult era such as Federer, Novak Djokovic, Rafael Nadal and Murray.
Zverev made it to the quarter-finals in a major tournament, when he did it at the French Open, in the 15th attempt of the competition. Federer achieved this in his eighth attempt.
