Sir Alex Ferguson admits the majority of Manchester United's World Cup stars are unlikely to feature in the club's Barclays Premier League opener against Newcastle next month.
England duo Wayne Rooney and Michael Carrick, France and South Korea captains Patrice Evra and Park Ji-sung, Serbia defender Nemanja Vidic and new signing Javier Hernandez of Mexico were United's six representatives in South Africa.
And Ferguson told Sky Sports News: "I have the feeling we'll probably not play them all but maybe one or two will play in it."
Rio Ferdinand is hopeful of being fit for the start of the season after injury prevented him captaining England, while Nani was in the squad which flew out for a pre-season tour of America after being ruled out of Portugal's campaign.
Owen Hargreaves' long-term knee troubles meant he never entered Fabio Capello's thoughts and a fresh setback will see him miss the resumption.
After a training camp in Chicago, United will take on Celtic, Philadelphia Union, Kansas City Wizards and the MLS All-Stars before the Chivas clash and the Community Shield against double-winners Chelsea.
