"It was definitely a tough match," the Russian said in his post-match on-court interview. "I am just looking forward to tomorrow. Roberto is a hell of a player.
"I feel like sometimes, when I have practised with him and played against him, that his ranking should be higher. There are reasons why it is not and I am going to try to do something with it tomorrow."
