Manchester United manager Sir Alex Ferguson doesn't want any of his players to play both summer tournaments in 2012.
The London 2012 Olympic Games follow the European Championships in Poland and Ukraine in the summer, with Ferguson having a number of players eligible for both.
Old Trafford is the home to a number of Fabio Capello's emerging stars, such as Phil Jones, Chris Smalling and Danny Welbeck, who would also be eligible for the London Games.
Ferguson is wary of having any of his side involved in both: "I wouldn't like to see our young players who might be involved in Euro 2012 then being selected for the Olympics."
The Scot is not the first Barclays Premier League manager to voice their concern over the possible physical strains young stars may be put under by being in both squads.
Arsenal manager Arsene Wenger has previously spoken of the importance for youngsters such as Jack Wilshere to rest during the summer.
Ferguson is not against international football and is keen to see his young stars represent their countries, but echoed Wenger by stating the importance of a proper break.
"Manchester United might well have a direct interest in this with our up-and-coming youngsters like Danny Welbeck, Phil Jones, Chris Smalling and Tom Cleverley now on the international scene," he added.
"I welcome their involvement at international level but if they go to the Euro finals they will need a break. I know they are young, fit and eager, but they will need to rest."
There was also a thinly veiled warning to Stuart Pearce, the man who has been appointed manager of the newly reformed Team GB Olympic football team.
"I am sure Stuart Pearce will bear this in mind. I certainly hope so because I wouldn't like to see them burnt out before they have really started."
