The LTA then recruited Cayer to help guide the wider group of doubles players, contributing to a boom that has carried seven Britons into the world’s top 55. More recently, he has been asked to help steer England’s new National Academy in support of head coach Nick Cavaday. But his role as “performance advisor” for Loughborough only covers around 50 days’ work a year.
Cayer’s influence is not restricted to doubles players. When Andy Murray wanted to remodel his serve slightly in 2016, he consulted two expert developmental coaches – Cayer and Ben Haran at Reeds School. He went on to win Wimbledon soon afterwards and finish the year as world No. 1.
According to Soares, “He [Cayer] is by far the best coach I’ve worked with. His tennis knowledge is insane. You can see what Jamie’s talking about, every guy that he works with, they improve, no matter what.”
