“The responsible thing would be to say, to let [George] make his own mind up, but I think I might be quite biased," William, a devoted Aston Villa fan, told BBC Sport.
“I haven't quite worked out how to play that yet,” William, 32, said. "Of course, he can support whoever he wants, but if he supports Villa, it'd be fantastic.”
William’s interview with the BBC, taped today, marked his first broadcast interview since the birth of Charlotte, his first daughter, earlier this month.
The prince, the president of the Football Association, the governing body of football in England, revealed how he became a diehard fan of Aston Villa, a team that has not won the FA Cup since 1957, according to the BBC.
“I was looking round for clubs to support and all my friends at school were either Manchester United fans or Chelsea fans," William said. “I didn't really want to follow the run-of-the-mill teams, and I wanted to have a team that was more middle of the table, that could give me the more emotional roller coaster moments.”
“To be honest, now looking back, that was a bad idea…I could have had an easier time!,” he joked.
Aston Villa will play in the FA Cup final this Saturday in Wembley, against Arsenal, and Prince William will be there in person to cheer on his team.
“I'd love to go to the odd match with him in the future,” William said. "I'll have to pass that by the missus, see how I can get away with it."
