'I don't know if he'll enjoy it or suffer' - Rublev on icon Safin as his coach

Rublev was defaulted from the Dubai Tennis Championships last year for unsportsmanlike conduct and has previously injured himself with his own racquet.

"He had his own struggles that he went through and I was always afraid to ask [about] those things, but I always wanted to," Rublev told the ATP Tour website., external

"When I found out he was looking maybe to work in tennis, it was like 'OK, I have to at least [try]'."

Rublev has yet to win a Grand Slam, having lost 10 times in the quarter-finals.

"Because if he feels I'm not listening, I don't think he will waste his time."
