John Stones says he felt like he knew nothing about football after joining Manchester City.
Pep Guardiola signed the England centre-back from Everton in 2016.
And Stones has revealed how Guardiola revolutionised his understanding of the sport.
“I honestly thought that I knew football to a decent degree after I left Everton,” Stones told Goal.
“Obviously, after I turned up and started training after a week or two I thought: ‘I literally know nothing about football’.
“His brain and how he sees different teams or tactics is, I can’t put it into a simple statement how he does it. Just how his mind thinks about football. And how he expresses that over to us as players – to get us to do what he wants, and what he thinks and what he believes – is incredible.”
Asked about Guardiola’s style, he continued: “Intense. And demanding. And I think that’s definitely why he’s been so successful over these six years that I’ve been with him. I think it comes from within him.
“It’s in his blood that he won’t stand for second best or standards slipping, and he does it every day and us as players now realise that every day is another time or another opportunity to improve.”
