Rublev hailed Federer as a 'true legend'
Russia's Andrey Rublev said "it is impossible to explain" after defeating Roger Federer in the third round of the Cincinnati Open on Thursday.
The Russian qualifier beat 20-time Grand slam champion 6-3, 6-4 and hailed the former world number one as a "true legend".
It was Federer's quickest defeat since losing to Franco Squillari in 54 minutes in Sydney in 2003.
"It is impossible to explain. I don't know. I mean, the way even how he (Roger Federer) finished the match, it was so amazing," said Rublev.
Rublev couldn't put his emotions into words after the match and said, "I told him it was a big honour and he said 'no worries'. The way he did it, it was amazing."
"Now I feel that he is a true legend and that is what my feeling inside is," Rublev said.
Rublev’s win sets up an all-Russian quarter-final with ninth seed Daniil Medvedev.
