After making excellent progress in recent weeks he is now back among the first-team ranks - and Fletcher hopes it remains that way.
"It's great to have him back and hopefully he can stay fit now and be a really important part of the squad," the Scot told manutd.com. "The biggest thing for us is the determination and dedication he's shown to coming back.
"He's come back in the last few days and surprised everyone. He seems to be fit and doesn't have any problems on the injury front."
