A pioneering tennis coach who helped a host of Grand Slam winners from a young age has died at the age of 91.
Nick Bollettieri founded his tennis academy in 1978 and went on to coach 10 players who reached world No.1. The likes of Andre Agassi, Boris Becker, Jim Courier, Maria Sharapova along with sisters Venus and Serena Williams were some of those that received expert coaching from Bollettieri.
Bollettieri, from New York, moved to Florida where he pioneered the concept of players living at his tennis academy to prepare them for life on the tennis tour. Agassi was one of the first stars from his tennis coaching structure and the American went on to win eight Grand Slam crowns.
