Speaking to the BBC via video link from Spain, Dettori explained: "At the beginning of the season, I was like I am 52. I watched Ronaldo at the World Cup starting on the bench, I didn't want to end like that. So I thought I'd call it quits and when I call it a day things will ease up.
"But the opposite happened, wherever I went I kept on winning. I did my farewells and I kept on winning and winning, and I thought 'Am I doing the right thing?'."
