The organiser of the International Champions Cup, Charlie Stillitano, is hatching plans to have Celtic take on Rangers - at Wembley Stadium.
The New Jersey-based football tycoon believes there would be worldwide interest in a first-ever match meeting of the Glasgow rivals outside Scotland and insists the national stadium would be a sell-out.
The International Champions Cup, involving 17 of the world's best teams, will take place this summer across the globe, focusing on matches in China Australia, the United States as well as Europe.
Celtic will play Barcelona in Dublin and host Leicester City in Glasgow while Manchester rivals City and United will meet in Beijing on July 25 as a total of 21 matches take place worldwide.
However, Stillitano believes there is room for further expansion in his pan-global event with Rangers a possible new invitee.
He told the Daily Record: "Celtic v Rangers would fill out Wembley, 100 per cent. That would be wonderful.
"We had Manchester United v Liverpool as the final of this tournament in 2014. They didn't want to play each other but they ended up meeting in the final in Miami and it was a great occasion.
"We have the Manchester City v Manchester United in China this year. If we can put on a Manchester derby in Beijing, we can put on a Glasgow derby. I think Wembley would be perfect for it.
"I love both clubs. I brought Rangers over to America under Dick Advocaat then Alex McLeish. I deal with Peter Lawwell regularly and we've brought them over many times.
"So for me, it would be a wonderful thing to do. And I don't think the safety issues would be insurmountable although it would have its challenges."
