"Michael has had his critics and, offensively, he's his biggest critic because he is used to scoring and providing goals and he hoped he would have done better," said Coleman to the CT.
"But I tell you what, defensively, we haven't half missed him because he knows where to be when we haven't got the ball and puts himself in positions to cut out passes, so we have missed him.
"David Bell has had a tough time with a lack of confidence, Carl Baker is trying too hard and that has all come at the same time, but those players got us into the position where we were a month ago and they will come again.
"Whether Macca can get through 90 minutes I am not sure but if anyone can do it he can.
"But we need to get a bit of confidence into those types of players and get a smile back on their faces and spring in their step and we'll be all right, but we have only got four games to do it."
