The Football Association has confirmed it has received an offer for Wembley Stadium.
The bid has come from Shahid Khan, the billionaire owner of Fulham and NFL franchise the Jacksonville Jaguars.
The offer is claimed to total as much as £800 million, although the FA has not disclosed any details.
A short tweet sent through its official spokesperson account on Friday read: "We can confirm that The FA has received an offer to buy Wembley Stadium."
Mark Waller, the NFL executive vice-president of events and international, has since confirmed Khan is behind the bid and says it is a "powerful sign" of a commitment to growing the sport in the UK.
