Heinze, meanwhile, is likely to miss the next three weeks after Sir Alex Ferguson revealed that the Argentine is still feeling the effects of the cruciate ligament damage he suffered11 months ago.
Despite representing his country at the World Cup, Sir Alex says Heinze still needs to build up his muscle strength.
"It's not quite what it should be," explained the United boss. "Gabby's therefore going to do some work in the gym over the next three weeks to build up the quadriceps.
"He did very well to get himself fit enough to take part in the World Cup after being out for so long, but I think he stretched himself and the consequences are he's not fully ready for us."
Gabriel Heinze is bracing himself for another fight but this time it's with his team-mates - not the injury problems he had to combat last season.
