Manchester United assistant manager Mike Phelan says Wayne Rooney has been making good progress during his time in the United States.
Rooney was sent to Nike's HQ in Beaverton for conditioning work after struggling for form and fitness in recent months.
United's medical team will assess Rooney on Monday after his return to England and, while he will not be fit to represent his country in next week's friendly against France at Wembley, Phelan suggested he could soon return to action.
"Wayne has been doing really well," Phelan told Key 103. "He has been training really hard, working morning and afternoon.
"Our people out there who are looking after him have been really pleased with his attitude and approach.
"All being well, he can have a nice easy flight back. We will see where he is at on Monday but we think he will have improved immensely."
