Manchester United statement reads:
“The Dutch left-back has not played so far this season, following an operation over the summer.
“Unfortunately, he suffered a setback during his rehabilitation, which required further surgery.
“This has been successfully completed and Malacia is now back at Carrington and working hard to be fit early in the new year.”
Malacia featured 39 times in his debut campaign across all competitions.
The good news for the Red Devils is that Luke Shaw is back fit
Shaw, 28, had missed three months after picking up a muscle injury at the end of August.
During his absence Sergio Reguilon has filled in at left-back.
