Hearts winger Andy Driver could be that player but the City boss is keeping his cards close to his chest and says that the player they looked at during the transfer window could now join in the summer.
"There is a player we are still looking at who has expressed a big interest in joining Coventry City but we don't think it will happen until the summer.
"But there is a whole host of players we are looking at."
The loan window opens on Tuesday and City may bring in someone on loan until the end of the season.
"The Chairman has been true to his word in the window but I imagine it will be the next window before we get in anyone permanent although we may get someone in on loan until the end of the season with a view to a permanent signing, " said Coleman.
