A love of football connects William to the country he will one day reign over in a way polo would not.

In the early hours of Monday morning, like millions of other football fans, the Prince of Wales stayed up in Windsor to watch England's memorable victory over Mexico. At Forest Lodge, his family home on the Windsor estate, he endured the delayed start, the intense atmosphere of the Azteca Stadium and the nerve-jangling end to the second half when a 10-man England agonisingly clung on to their lead. He'd watched every other England match too as you'd expect from the Patron of the Football Association. He knows the England set-up well and has been in direct contact with players and staff during the tournament – several England footballers have Prince William's personal phone number. If England make it to the World Cup final in New Jersey on 19 July, Prince William will fly over as an official representative of the FA and the royal family's most ardent football fan. And his passion for the game has often been at its most raw on the royal family's social media platforms. Royal posts can be tame affairs. The usual pattern is a reminder of the day's engagements, a clip of a speech delivered, sometimes an official comment around an event alongside the day's best pictures. But on 20 May this year, Prince William's official accounts loosened up just a bit. "UTV! VTID" they screamed alongside a red love heart and the muscular arm emoji. For those not in the know, that translates as "Up the Villa" and "Villa Till I Die." Not your typical royal social post.
