Boris Johnson, the mayor of London, conducted a little #askboris session on Twitter and one of the actually serious questions he was asked concerned the possibility of locating an NFL team in the city.

Johnson’s answer? “We are working hard on a deal” with “high hopes for Tottenham in the next few years.”

Over the summer, the NFL announced that, starting in 2018, teams would play a minimum of two games a year at Tottenham Hotspur’s new stadium in London over 10 years. The English Premier League club is in the process of designing a new, 61,000-seat home field to replace White Hart Lane, which is nearly 116 years old.

The new stadium, scheduled to open in 2018, is estimated to cost around $615 million will have a retractable grass field with an artificial surface underneath. The artificial turf would be used for the American football games.

The NFL will play three games (Dolphins-Jets on Oct. 4, Jaguars-Bills on Oct. 25 and Chiefs-Lions on Nov. 1) in London this season, with all three kicking off at 9:30 a.m. Eastern time. Eleven NFL games have been played at London’s Wembley Stadium since 2007 under a contract that runs through 2016, a deal the NFL said over the summer it hopes to extend.

“With growing enthusiasm for the NFL in the United Kingdom, we are committed to hosting NFL games in world-class venues and are excited to partner with Tottenham Hotspur to play games at their future stadium” NFL Commissioner Roger Goodell said in a statement in July. “We share a vision and commitment to creating the best experience for our teams, fans and the local community.”
