Prince William hosted a private meeting with the new England soccer manager this week.
The future king is President of the Football Association and was keen to hold talks with Sam Allardyce, aka Big Sam, who was given the job earlier this summer following England's dismal performances at the European championships.
A source told the Daily Mail newspaper: "His Royal Highness is President of the Football Association and takes the role very seriously."
Another source joked: "It's Big Sam meets Little Wills."
In April, the Duke of Cambridge celebrated 10 years in his role at the FA and in his speech said its governance structure is in need of reform.
He said:"Our governance structure is in danger of falling short of modern standards of best practice. As the country's national sport, we ought to be leading the way."
The father-of-two - who took over the presidency from his uncle, the Duke of York - appeared to publicly back outgoing chairman Greg Dyke's efforts to reform the FA Council by making it more representative and diverse.
The 34-year-old royal added: "There is a wind of change blowing through global sporting governance and we need to ensure we do not get left behind.
"I know the organisation is currently reviewing this issue and there is an opportunity to seize the initiative by the way in which we reform ourselves.
"This is an emotive issue, and it is one that you all have a stake in deciding."
