In an interview the former world No. 8 Mikhail Youzhny commented on Daniil Medvedev's breakthrough on the men's Tour. Youzhny said: "I did not expect Daniil to crack top five rankings this year. I think he had good results last year, but there was also some improvement.
Playing at a high level for three tournaments in a row, playing two Masters 1000 finals, was unexpected. You cannot deny he can win US Open or reach the final. But I would not be in a rush. In a future, I think it's possible.
I think Daniil still has the potential. The match with Rafael Nadal in Montreal showed what he needs to work on. Predicting how high he can go on the rankings is not that easy. And it will depend not only on him, but also on his game's rivals."
On Karen Khachanov, he added: "He dropped a bit in the beginning of the season which was normal. He also tried changing racket but the second half of the season will be better." On Andrey Rublev, he concluded: "Starting from last year, he has been struggling.
Your health condition influences your training. In order to get good results not only once but throughout the year, like Medvedev and Khachanov, something needs to change in training."
