Speaking to The Mirror, the award-winning writer revealed that the prospect of retirement was one of the topics he discussed with Hamilton ahead of his upcoming transfer.

"He says he knows when the end of his career will be, he has got this very clear plan ahead of him.
"He said it is really meaningful to him, the fact that he has won all these races with Mercedes and he has been on this journey.
"The one thing he had not done and he just thought, ‘I do not want to walk away and go, I wish I had done that'."
