The NFL have had substantive talks' with officials in London about hosting the Super Bowl in the capital.

The unprecedented move could see the world's biggest sports match played outside of the United States for the first time in 2013.

Wembley has already hosted two regular season NFL games and the Tampa Bay Buccaneers will face the New England Patriots at the venue in October.

The league's commissioner Roger Goodell has previously admitted an interest in bringing the game to London but this is the first confirmation of discussions. Wembley would be the favourite
to host the occasion, although Twickenham is also being considered.

“We've spoken on what it would take to bring
it over,” said events vice-president Frank Supovitz. “The city has all the facilities needed and in great quantity.”

Supovitz was talking in New York City, where the NFL Draft will take place this weekend. “We have had substantive conversations with the city of London,” he told BBC Sport.

The venues for the next three Super Bowls have already been decided, with Dolphin Stadium in Florida, Dallas Cowboys Stadium in Texas and the Lucas Oil Stadium in Indiana putting together successful bids.

Last year's Super Bowl in Tampa was the most watched TV programme in US history with an audience of 151 million.
