Manchester United manager Louis van Gaal says striker Wayne Rooney will soon be back in action but midfielder Bastian Schweinsteiger will stay on the sidelines for months.
The Red Devils host Everton on Sunday afternoon with a number of key players again out injured.
Midfielder Ander Herrera and winger Ashley Young are also on the way to recovery but will not feature against the Toffees.
"Wayne [Rooney] is doing great," van Gaal told MUTV.
"He has more or less the same injury as Basti [Schweinsteiger] has now. He's doing great. Today he has trained on a lower level with a little bit of skill training, so with the ball. It's going very good with him.
"[Bastian] Schweinsteiger was injured already before the matches.
"I think it was on the second day of training. That's a big blow for us and also for the national team.
"You can never say anything about that [missing the rest of the season] because he's started his rehabilitation. You have to wait and see.
"He is a tragic injury because the expectation is not so good for him in respect of of the European Championship [in the summer], but you never know!
"He has to work hard for that because he wants to play and the Germany national manager wants him to play, so I hope that he can reach that, but it shall be difficult.
"[On] Monday, he [Luke Shaw] is back on the training pitch for the first time but that's a start with the physio, not a start with the trainer coach. Wayne is already with the trainer coach.
"They [Ander Herrera and Ashley Young] are coming back. Young and Adnan [Januzaj] played for the Reserves last Friday in the international break, in a game between each other. So a lot of players are coming back."
