The 23-year old USA international is on loan at Villa Park from German Bundesliga club Borussia Monchengladbach and assistant manager Gary McAllister has indicated that he may remain in the English Midlands after his initial spell runs out.
"Michael has done enough on the training ground to suggest there might be something come the end of the season because he has an honest, hard-working guy as well as a good player," he told the Express and Star.
"It's true that it has been hard to play him at a time when we have had senior experienced players available in the situation we have been in.
"And that is purely all that has held him back, nothing else, because his attitude has been top draw.
"He is a fantastic professional for such a young guy - he has captained his country don't forget and he is a top player.
"With four games to go it is something that Gerard and I will be speaking about because there are a few guys in the same boat as Michael.
"We are aware of these things. There are three or four players who we feel that if we have got ourselves into a better position earlier in the season then certain people would get more game time.
"But we're still very much aware that we need to keep this run going and, when a team does well, you don't want to be making big changes or changing things for the sake of it."
