"Our role would be to provide a world-class venue," he said. "[The FA] will have a pool of money of about £600m that can be invested into the core mission of the FA, which is English football and their ultimate goal of winning a World Cup. Wembley is a great stadium and you want to get it configured to hold Super Bowl and World Cup finals."
Khan admitted it's a bit "premature" to discuss a Super Bowl in London since no deal is in place for the stadium. Conway previously reported the billionaire offered £900 million ($1.2 billion) for it.
In 2007, NFL Commissioner Roger Goodell said the league would consider playing its championship game overseas.
"There's a great deal of interest in holding a Super Bowl in London," he told reporters. "So we'll be looking at that."
He has also kept open the possibility of a franchise being based in the English capital, though he noted there are still logistical issues that would need to get worked out.
"We're still trying to make sure we can do it from a proper competitive standpoint," Goodell said in 2016. "You don't want to put a team over there and have them at a competitive disadvantage. And then the logistics, how you work that out. That's not easy."
Mark Waller, the NFL's executive vice president of international, told Albert Breer of The MMQB in September that 2022 is a realistic target date for a London team.
While nothing is set in stone, Khan buying Wembley would be a major step toward giving him the resources necessary to pique the league's interest.
