The American died on Sunday after coaching players like Andre Agassi, Serena Williams, Maria Sharapova, and Boris Becker.
He established the Nick Bollettieri Tennis Academy, which is now the IMG Academy, and has long established a reputation as one of the sport’s most recognizable instructors.
Bollettieri also coached Tommy Haas, who on Monday gave him an emotional tribute.
The German posted on Instagram: “So many memories, I am not sure where to begin. Nickiiiii, that’s how I have called you for the longest time.
“Thank you for your time, knowledge, commitment, expertise, the willingness to share your skill, your personal interest in mentoring me and giving me the best opportunity to follow my dreams.
“You were a dreamer and a doer, and a pioneer in our sport, truly one of a kind.
“I surely will miss you around the academy, our tennis talks, miss showing of [sic] your tan, white teeth and body fat, miss watching you do Tai Chi, miss playing golf with you watching you try to cheat, eating a Snickers bar and running for the bushes, and hearing all about your plans even at the age of 91.
“Thanks again for everything……..
“RIP Nickiiiii.”
Monica Seles and Jim Courier were among the other players who were coached by Bollettieri.
