Based on the description, it seems like a partial re-working of the previous book, with only profit in mind, as GSM mentioned.
"Who is Ivan Lendl and How did he turn Andy Murray, a four-time finalist - into the first British winner of Wimbledon in over 70 years? Mark Hodgkinson goes in search of Lendl 'the man behind the iron curtain' - his brutally tough childhood in communist Czechoslovakia, who defected to the US to pursue his dream of becoming a tennis legend. Competing against the loud-mouths of McEnroe and Jimmy Connors, who despised his ruthlessly scientific approach to the game, he lost four major finals before cracking McEnroe to go on to win 8 major titles. His greatest obsession though was Wimbledon, which he twice missed the French Open to prepare for, but still never won. When Murray took him on he had never coached anyone before, and failure seemed to be the only thing they had in common. Ahead of Wimbledon, when Murray will aim to defend his title, Mark Hodgkinson reveals through interviews with all the protagonists, including Lendl and Murray, what the magic formula was that Lendl used to turn Murray into a champion. It will left the lid on their relationship - one of genuine friendship as well as brutally hard work and the similarities in their familial upbringing and their shared obsession with the minutiae of the game that made this left-field combination the most successful in British tennis history."
There are seven sentences in that description. Four involve Murray.
If it is meant to be a biography of Lendl, he's got to be PO'ed that the focus of his life is now mostly on the few years he worked with Andy. He's now "the man who made Murray."
