Twelve months ago Jones was as big a part in the United side as any of the other regulars to the side, but since the final day of last season the 20-year-old has been out of the side with a back injury picked up in pre-season training.
After recovering from the spasm the young defender then had to have surgery on his knee in September.
Jones now has to fight back and he will be looking to impress at the Turk Telekom Arena where United take on Galatasaray.
“It’s a big day for Phil Jones because he has been out all season,” said Sir Alex to the MEN.
“He has done enough training to make his fitness is okay and I am looking forward to bringing him back.
“He has had different types of injuries. He is young and he is still to develop physically because he is only 20 years of age, so he has plenty of time.”
