The mould-breaking and hugely charismatic tennis coach Nick Bollettieri has died aged 91.
Bollettieri first established his eponymous academy in 1978, and before long students were living and training full-time in Bradenton, Florida.
With his deep tan and wrap-around sunglasses, Bollettieri worked his pupils extremely hard, and changed the face of tennis coaching.
"You were a dreamer and a doer, and a pioneer in our sport - truly one of a kind," former world number two Tommy Haas said in a tribute.
Sabine Lisicki - runner-up at Wimbledon in 2013 - said Bollettieri "shaped the game of tennis".
