#10 Harry Hopman

The most decorated Davis Cup coach of all time is Australian tennis legend Harry Hopman. He won a total of 16 Davis Cup titles in his 22 year spell as coach of the Australian Davis Cup Team between 1939 to 1967.
Some of the most famous players under his tutelage include Ken McGregor, Frank Sedgman, Lew Hoad, Rod Laver, Ken Rosewall, John Newcombe, Tony Roche, Roy Emerson, Ashley Cooper and Neale Fraser.
Hopman managed to earn tremendous respect even from a teenage John McEnroe; the notoriously short-tempered American would always address him as “Mister”. Hopman helped nurture McEnroe into the tennis legend that he would become.
The Australian opened the famous Hopman Tennis Academy in Florida, which continues to produce top tennis talent even today. Legends like Rod Laver and Roy Emerson have on numerous occasions spoken about the influence that Hopman had in their careers.
The Hopman Cup, played in January every year, is named after him. Hopman was inducted into the International Tennis Hall of Fame in 1978.
