Premier League chief Richard Scudamore is still in favour of adding a controversial 39th game to the season. The idea of playing an extra round of fixtures abroad was first floated in 2008, but drew fierce criticism from football fans and the media.
But Scudamore told the BBC: "The clubs wanted it then and they all would still probably want it now.
"It will happen at some point - whether it is on my watch, who knows?"
Premier League clubs routinely travel abroad on friendly tours, with Manchester United drawing a record US crowd of 109,318 when they played Real Madrid in Michigan this month.
United and Liverpool then played out the final of the International Champions Cup in front of more than 50,000 fans at the Sun Life Stadium, home of the NFL's Miami Dolphins, on 5 August.
"What has been interesting over the summer, particularly in the US, watching those audiences, you could argue that we don't need to do it [bring in the 39th game]," he said.
"To get 102,000 to what we would call a pre-season friendly - you wouldn't get more even if there was three points, six points, or even nine points riding on that particular game."
