Age: 56

Coach of world number two and Wimbledon second seed Andy Murray from 2012 to 2014 then resumed working with him earlier this month

Grand Slam finals: 19

Grand Slam wins: 8 French Open 1984,’86,’87; US Open 1985,’86,’87; Australian Open 1989,’90

Grand Slam record against rival coaches: Beat John McEnroe, Milos Raonic’s coach in 1984 French Open final and 1985 US Open final, avenging his defeat in the previous year’s final; lost to Boris Becker, Novak Djokovic’s coach in the 1986 Wimbledon final, 1989 US Open final and 1991 Australian Open final

Wimbledon record: Struggled on grass more than any other surface, reaching the Wimbledon final just once when losing to Becker in ‘86

What he brings to Murray: When the reasoning behind his initial appointment was explained on the basis that the Czech understood better than anyone how to cope mentally with the pressure of having lost his first four Grand Slam finals it made perfect sense, all the more so when the Scot then won his Olympic singles title during their first season together and achieved his Grand Slam breakthrough at that year’s US Open before that even more special Wimbledon win the following year. Two stubborn men then went their separate ways as a result of the intensity of the schedule, but a couple of seasons of near misses, albeit interrupted by further evidence of Murray’s team ethic with his astonishing contribution to another historic British win in the Davis Cup last year, has encouraged a compromise as the two have found a way to work together again, achieving instant success with Murray’s record breaking fifth Queen’s Club win.
