#2 Boris Becker
German Boris Becker is a six-time Grand Slam Singles champion and the youngest Wimbledon men’s champion of all-time at just 17 years.
Novak Djokovic hired Becker as his full-time coach in December 2013. In just three years, Becker contributed to six of Djokovic’s 12 grand slam triumphs and 14 of his 32 ATP Masters 1000 titles. In 2016, Djokovic and Becker parted ways by mutual consent. Djokovic completed his Career Slam at the French Open of 2016 under the guidance of Boris Becker and long-time coach Marian Vadja.
Becker presently serves as an analyst for BBC and is regularly seen at the commentary box during Wimbledon giving his views. He was in 2017 appointed as the coach of the German Tennis Federation.
