William is a long-standing Villa fan from his Eton days and it is clear he expects George, third in line to the throne after his father, to follow suit.
"When (Aston) Villa thrash Man U at Villa Park, my son will be there," he said in a video message released ahead of the Football Association's 150th anniversary gala dinner at the Connaught Rooms in central London.
The Duke, who is the president of the FA, will make the opening address at the dinner which will be attended by guests from around the world, including FIFA president Sepp Blatter and his UEFA counterpart Michel Platini.
Three members of England's victorious 1966 World Cup-winning side - George Cohen, Martin Peters and Sir Geoff Hurst - will also be present.
In the video William talks about the great pride he takes in his role at the FA.
"I've always loved football since I was a young boy," he said.
"I've never got any better at it but I keep saying to myself if you keep trying, eventually something will happen.
"It's always meant a great deal to me being president of the FA.
"There's a lot of good that football can do around the world, and in this country.
"But globally it is a huge force for good and a lot of people love, respect and enjoy their football more than anything else in their lives."
Thanks to his intervention, history was made earlier this year when Buckingham Palace played host to its first football match.
Civil Service, the last remaining club of the group which formed the FA on October 26, 1863, lost 2-1 against Polytechnic FC in a game that received official sanction from the Queen.
"There was one person I needed to get permission from, my grandmother," said William.
"She was extremely supportive, but there was a little bit of a sweating moment for me having to ask her, with the possibility that her lawn might turn into a massive quagmire."
