Ferrer detailed the start of their relationship and that Zverev's persistence paid off in the end and he believes Grand Slams could be in the offing.

“There were other proposals, but Zverev called me three times to ask if I could be his coach,” Ferrer said during an interview with Punto de Break. “The first two I told him that I couldn’t, that I had other things in mind, but during confinement (lockdown) he called me a third time. I liked that, that he was the one who contacted me, he encouraged me to try.”

“I think he has a lot of room for improvement mentally and tennis too,” Ferrer commented. “Maybe in playing more forward, or certain technical aspects that he can polish.’

“We are talking about a player who is already very good, but by improving certain tennis and mental aspects he can win Grand Slams and be very high. You always need to evolve and improve in your game, this is what motivates me the most, that even knowing everything that has already won, we know that it can still be better. I believe it 100%.”
