London is “on the cusp” of being awarded an unprecedented four NFL fixtures next year after a sell-out clash between the New York Giants and the Los Angeles Rams at Twickenham, Sadiq Khan has told the Standard.

The Mayor was speaking after talks with the boss of the world’s wealthiest sporting club competition, NFL Commissioner Roger Goodell, who was in London to watch the first non-rugby match staged at the home of the English game in its 107-year history. Mr Khan said he was optimistic that the NFL will confirm a step up from three to four gridiron games in London when the 2017 season schedule is unveiled towards the end of the year.

He said: “I want London to be the business capital of the world, the cultural capital of the world and the sporting capital of the world. I hope that the Commissioner — no pressure — will have good news in the next 45 days. Just imagine if we went from three to four.”

Mr Khan said he also wants to see NFL play-offs and even a Super Bowl staged in London as a longer-term ambition.

Yesterday’s match at Twickenham, attended by 74,000 and won by the Giants 17-10, was the culmination of three years of talks between the NFL and the Rugby Football Union, which owns the stadium. It was the first NFL fixture on English soil not played at Wembley since regular season games started in 2007. The NFL has also signed a deal with Spurs to stage two games a year at their new stadium from 2018.

Mr Goodell said the success of yesterday’s clash made it more likely the NFL would be able to award more games to London. He said the NFL is still investigating the practicalities of permanently basing a franchise in the capital. He said: “The growth has been phenomenal.”

The last match of this season’s “International Series” is between the Cincinnati Bengals and the Washington Redskins at Wembley on October 30.
