Arsenal manager Arsene Wenger believes it will not be long before there is no room in busy football schedules for international friendlies.
England suffered their first defeat under new boss Fabio Capello when they were beaten 1-0 by a under-strength France side in Paris on Wednesday night.
Wenger was at the Stade de France, as a pundit for French television and he feels such encounters have little meaning now, with everyone so focused on competitive games.
"I am scared that in the modern game, there is no room any more for friendly internationals - not because countries take our players, just because people will not be interested in that any more," Wenger said.
"There is nothing at stake. People want to see competitive games. Maybe I am completely wrong but in the end you get people to travel and it is good as an experiment for a manager to work on things.
"But, is it in the long term feasible for people to travel and spend their money to watch this kind of game? I am not sure."
The Arsenal boss continued: "They are slowly starting to cut the number of international games because they have no meaning any more in the modern game. People want to see competitive games.
"You sit here today. You can't say England were fantastic or France were fantastic. Straight away you say 'but it was only a friendly'.
"In fairness I watched the game last night and you always felt it was a friendly game with 5% missing between a friendly and a competitive match."
Arsenal played host to an international on Wednesday night, with more than 60,000 people turning up at Emirates Stadium to see Brazil take on Sweden.
The Gunners boss believes the time would be better spent having squads assemble for a few days rather than taking on opposition just for the sake of it.
But Wenger did admit that the matches still hold meaning to the players - with his squad full of internationals from around the globe.
"They could be replaced by training camps," Wenger said.
"You have to think about it if attendances and television audiences go down. I saw many friendly games last night with half-empty stadiums.
"I believe frankly that it means a lot to my players. When I speak to my players, they want to do well in the European Championship, they want to do well in the World Cup.
"It really matters to them. You could see a guy like [David] Beckham. He was ready to die to get his 100th cap.
"If he wasn't and it didn't matter, he would not have done that.
"It matters to them, but it is still a friendly - it's low key, the guy plays last night and next week he has a Champions league game and he doesn't want to miss that game.
"So subconsciously, you miss a fraction and that makes a game less interesting.
Despite the disappointing result in Paris for England, Wenger maintains it is all part of the learning process for their new Italian coach.
"I wouldn't draw any conclusions from last night's game because I think that at the moment Capello is in an experimental period," he added.
"He played a technical team first of all with 4-5-1, but England lacked a bit of penetration. "Then a more British style with Crouch and Owen up front, where they were then dominated in the middle of the park. I feel certain he will try to find a mixture between these two styles."
