Pete Cowen

Cowen is one of the most respected coaches in the world – and he is much needed. Known for his straightforward golf course, his cast list reads as Who’s Who of golf – working with Brooks Koepka, Rory McIlroy, Henrik Stenson, Ian Poulter and Graeme McDowell. Prior to the epidemic, he realized that he normally clocks up 250,000 air miles each year. He does not charge his players, instead he gets a percentage of the player’s win, depending on their results. He has three academies – two in Dubai and one in Rotherham.

David Leadbetter

David Leadbetter does not do anything simple but there is no doubt about his credentials. He is a man who has been tasked with rebuilding Nick Faldo’s golf course. Faldo had enjoyed a good start in his playing career but knew he did not have a game to win majors, so he sought Leadbetter, an unknown coach at the time. And together they rebuilt him and turned him into a great six-time champion. Leadbetter has worked with many top female players, most notably Michelle Wie.

Chris Como

Como was mostly unknown but all that changed in 2014 when Woods decided to hire him as his fourth coach. Como has a reputation within the sport as a golfer. He knew one or two things about the injury, and what could be done to reverse the pain and reduce the stress and strain, so he was naturally ready for Woods at a time when the American was trying to regain his battered body.

Denis Pugh

Known for his outspokenness on Twitter, Pugh is a professional analyst and golf coach. He has worked with a number of elite players, but his most famous student, Francesco Molinari, has helped him transform into a regular European Tour player and a world-class player.

Peter Kostis

Kostis is probably best known for his work on the microphone but is also a highly respected public figure Paul Casey and Bernhard Langer among his students. He has another celebrity claim – he taught Kevin Costner to play golf for the Tin Cup film. And Costner is now a golf addict.
