Manchester United coach Louis van Gaal says defender Marcos Rojo will not undergo surgery to fix his shoulder problem.
The Argentinean was stretchered off with oxygen mask after suffering a dislocated shoulder against Manchester City and is expected to be on the sidelines for at least six weeks.
"When I want to select the same line-up, I cannot," van Gaal said during Friday's press conference.
"It's the same every week. It is like it is and I don't want to complain or cry because I have great belief in the players, myself and my staff.
"Also the supporters who are supporting us despite the results.
"Marcos [Rojo] dislocated his shoulder but did it in a positive way.
"We don't need to operate on him. It's a relief but maybe, with this injury, it is very difficult to prevent it from happening again. That is the problem.
"He saw a specialist yesterday evening who said the conservative way to heal it is best. For him, it was positive.
"Always with these injuries, I cannot change that. The human body has been made by God - not by me. Conservatively, it can be less than six weeks. If we have to operate, 12 weeks.
"[Chris] Smalling is suspended. Evans and Jones are still injured. So I have to solve a problem but I don't want to say who is playing yet."
