Tottenham Hotspur's new stadium was given a visit by Roger Goodell, the commissioner of the NFL, on Monday.
He was joined by the club's chairman, Daniel Levy, who took the American Football chief on a guided tour of the new 61,500-seater ground, which is set to open next season.
Goodell also brought along NFL executive vice president Mark Waller as he took in the progress at the stadium in north London.
Tottenham and the NFL have a 10-year agreement to stage International Series matches at the stadium starting in 2018, and Goodell was impressed by what he saw.
