Owen Hargreaves could be back in a Manchester United shirt shortly, according to the 29-year-old former Bayern Munich star's surgeon.
The England international has spent almost two years trying to recover from a career-threatening tendinitis problem in his knees, with his latest setback coming during the early stages of pre-season training.
He was sent back to Dr Richard Steadman in Colorado for more rehabilitation work after complaining of pain in his knees.
Steadman told the BBC: "Things are looking good for Owen, it's all worked out. He's close to playing fitness, although it's obviously up to United to decide when he plays a match.
"The problem was with the tendon attached to the patella on each knee, which is difficult to resolve.
"After the surgery, the key was rest and working hard on recovery. Owen has spent a lot of time with us here in Colorado and he has never given up.
"The recovery was arduous and took a long time but his condition looks promising now."
