Minnesota Vikings president Mark Wilf has said that he is "fully supportive" of the NFL's efforts to grow the league's international audience.

The NFC North side will play the Pittsburgh Steelers later today in the first of two games being held at London's Wembley Stadium this year.

Wilf, whose brother purchased the club in 2005, told Sky Sports News: "From a Minnesota Vikings perspective we are fully supportive of growing the game internationally.

"It is a tremendous game and I think the fans here are starting to appreciate that more and more, so if that's the direction that might be, a franchise or other things along those lines, we're supportive of those efforts to grow the game internationally.

"There is no question that the fan excitement and fan interest grows and grows a little bit more. It is a contagious type of feeling to watch a game. The kind of experiences you have where families and communities come together around a game of football are things we want to see growing around the world every day."

It is estimated that more than half a million fans attended the NFL Block Party on Regent Street yesterday.
