Roger Goodell has reiterated his desire for an expansion franchise based in London. Goodell admitted there is a strong case for a London team, while he also wants a new organization in Los Angeles for the first time since 1995.
The commissioner is encouraged by the huge success of the International Series games at Wembley Stadium, and he admitted continued support could earn London its own NFL team.
Each game at Wembley has attracted crowds of around 80,000, and Goodell said: "I think it's possible if we continue to have success in London that we would have a franchise there."
"I don't know which of Los Angeles or London will be first and I'm not sure I care. I'd like to see if we can be successful in both ultimately."
In his press conference in New York, the venue for the first cold climate Superbowl on February 2, the 54-year old admitted that other cities with similarly cold weather would be given the chance to host the showpiece event.
"This is obviously innovative and it's something new but it's also unique because it's New York," said Goodell.
"Every city can't host a Super Bowl just because of the sheer enormity of this event. And it's not just a football game.
"We have a week full of events, we probably have well over 150,000 coming in to the New York region for this event."
