In his pre-match interview with MUTV, the boss reported:
“I had a word with him before training yesterday to say I'm not going to rest him. But then he rolled his ankle in training so he had to stay at home.
“Hopefully he'll be okay for the weekend but I'm not sure.”
Solskjaer went on to reveal that Maguire's fellow signings in last summer's transfer window, Aaron Wan-Bissaka and Daniel James, are also injury doubts for United's next match - the home Premier League derby against Manchester City on Sunday afternoon.
