Sir Alex Ferguson has hit out at Roy Hodgson's suggestion that every international break 'should be taken seriously'.
England boss Hodgson claimed on Thursday that players and managers saw the FIFA fixture list as a 10-day rest period, and said that Premier League coaches have 'no excuse' for sending their star men to Dubai.
"I'd still like to see it as a time when players go to play for their international teams," Hodgson told reporters at the Soccerex conference.
"These breaks are being seen as the 10-day break that players don't always get during the season.
"It concerns me that (English football) is guilty of accepting 'It's the international break so we can give the player 10 days off or go to Dubai'. If you're a club manager now, you've got no excuse.
"You can easily plan your time around these blocks. If your players need a rest, it's not obligatory that it has to be during the international break. It can be during the other 40-odd weeks of the year.
"We have to be careful when talking about overplaying.
"We take something as read because it is thrown at us. The season might be 55 games long, but you show me how many players are playing 55 games?"
But the Manchester United manager has slammed those claims, suggesting that international football hinders the club game.
"I think international football interferes with the clubs' ambitions, friendly games for a start. For the last decade they're playing a friendly game a Wednesday before the season starts, tell me the sense of that," he told reporters on Friday.
"It doesn't matter which way you look at it, clubs managers are always in disagreement with international football, particularly in friendly situations.
"I've no issue at all with the competitive part, the European Championship and the World Cup, I think the players should always be available for that, but you can't tell me that should apply itself in the friendly games."
