A threadbare City squad lost only once in 10 games in all competitions but a boost in numbers has coincided with back-to-back defeats to Cardiff and Derby.
"A month ago, when we had probably the worst injury list we've had and we had three or four academy kids on the bench, we were winning games because we had a little bit of fear that if we weren't at it then we were going to get beaten," said Coleman. "But it seems the more bodies we get back and the thicker the squad gets, our performances are dipping - and that's not right. I'm not having that.
"So I've told the players I won't pick the team against Wolves until the day of the game on Saturday. I'm seeing who is ready for it in training this week.
"Forget what they have done in the past, we'd lost one in 10 but now we have lost two on the bounce - they're the statistics. So who's got the hunger and who wants to play? It's about who's got enough belief and desire."
