Wan-Bissaka complained of a sore back after last weekend's draw at Everton and was ruled out of the Derby game, while James sustained a knock in the Europa League win over Club Brugge and has missed the last two matches.
Speaking about Maguire, who turned 26 on Thursday, the United boss said: "Well it's touch and go because he rolled his ankle and he twisted it, but hopefully he'll recover quickly. I wasn't going to rest him today (against Derby) so I didn't give him a day off birthday-wise, but I hope he'll be fit."
On the chances of Wan-Bissaka and James being fit, he added: "I hope so but none of them have been training yet since the last game. We've got to look at them Saturday probably. Friday is the recovery day."
